No, axolotls cannot live out of water. They are obligate aquatic neotenic salamanders that depend on water for skin-based respiration, gill function, and skin hydration. Brief handling under 1 to 2 minutes is sometimes unavoidable during tank maintenance. Paludarium setups, forced metamorphosis, and treating axolotls like terrestrial amphibians are all unsafe.
Why are axolotls permanently aquatic?
Axolotls are obligate aquatic neotenic salamanders that reach sexual maturity without undergoing metamorphosis. Their bodies retain the larval form for life, with external feathery gills, thin permeable skin, underdeveloped lungs, and limb musculature suited to underwater locomotion. They lack the metamorphic transition that allows other salamanders to live on land.
Neoteny is the central biological reason. A tiger salamander (Ambystoma tigrinum) is the axolotl’s closest land-dwelling relative. It hatches as an aquatic larva with external gills. During metamorphosis it loses those gills, develops lungs fully, and thickens its skin. The adult tiger salamander walks onto land. Axolotls never take that step. They retain the larval body plan for life. The Frontiers in Endocrinology review of axolotl thyroid-dependent development frames the underlying biology directly. The axolotl typically does not undergo a metamorphosis. Axolotls are paedomorphic because they express ancestral juvenile traits in the adult stage of life (source: Frontiers in Endocrinology, Crowner et al. 2019).
The hormonal mechanism is well documented. Thyroid hormone levels stay low through larval development. They do not rise at the point where tiger salamanders begin to metamorphose. The hypothalamic-pituitary-thyroid (HPT) axis exists in the axolotl. The peripheral tissues are responsive to thyroid hormone treatment. The signal that would activate metamorphosis simply does not arrive (per Frontiers in Endocrinology, Crowner et al. 2019). This is not a deficiency or a disease. Neoteny is the axolotl’s evolved reproductive strategy. Wild axolotls reproduced this way in Lake Xochimilco for thousands of years.
The species’ habitat reinforces the obligate-aquatic biology. Britannica records that the species is found only in Lake Xochimilco within Mexico City (source: Britannica). The lake sits at high altitude. Animal Diversity Web lists the elevation at approximately 2,274 meters (source: Animal Diversity Web). The lake-system biology is mentioned here only for context. The relevant fact for the out-of-water question is that the species evolved as a permanently aquatic animal in a permanent freshwater lake.
The hub axolotl care guide covers the broader husbandry context for axolotls as obligate aquatic pets. The axolotl facts guide covers the species’ biology and the neoteny mechanism in more detail.
What “obligate aquatic” actually means for husbandry
Obligate aquatic means the animal must remain submerged in water at all times for normal physiological function. This is distinct from three nearby categories. Facultative aquatic species like frogs spend part of their life in water and part on land. Semi-aquatic species like turtles need water but also basking surfaces. Amphibious species can move between water and land routinely. Axolotls fall into a narrower category than any of these. They cannot leave water voluntarily. They cannot be housed in any enclosure that includes accessible dry surfaces. A fully aquatic tank with no land area is the only correct enclosure type. The tank setup guide linked above covers the water-depth and lid-security specifics.
How do axolotls breathe and why do gills need water?
Axolotls use three respiratory pathways, all of which depend on water. Skin (cutaneous) respiration is the primary pathway and requires the skin to remain moist for gas exchange. The external feathery gills add surface area for additional oxygen uptake. The lungs are underdeveloped and only supplement the other two pathways through occasional surface gulping. In air, two of three pathways fail immediately.
Cutaneous respiration is the dominant gas-exchange mechanism. Axolotl skin is thin and permeable. Dense capillary networks sit just beneath the surface. Dissolved oxygen in the water diffuses directly through the skin into the bloodstream. Carbon dioxide diffuses out the same way. The process requires the skin to stay moist. The Libertyland Axolotl Rescue respiratory-anatomy guide states the point bluntly. The main respiration is not through using their gills. It’s their skin (source: Libertyland Axolotl Rescue respiratory anatomy). In air, the skin dries within minutes, the protective mucus layer degrades, and gas-exchange efficiency drops sharply.
The external feathery gills provide a secondary oxygen-uptake pathway. The San Diego Zoo axolotl page records that axolotls use prominent, feathery gills to breathe underwater (source: San Diego Zoo). Each gill filament is technically a fimbria. The filaments contain blood vessels separated from the water by a very thin membrane. Oxygen moves across that membrane by diffusion. The filaments also carry gill rakers. The rakers filter debris and parasites from the water passing over them. Out of water, the filaments clump together under gravity. Without water to separate them, the surface area for gas exchange collapses within seconds.
The lungs provide the third and least-efficient pathway. Axolotls have small lungs. They occasionally gulp air at the water surface. The Libertyland anatomy guide describes the behavior directly. Keepers may see their axolotl swim to the top and take a little gulp of air. This is the lungs at work (per Libertyland Axolotl Rescue respiratory anatomy). Occasional surface gulping is normal, especially in warmer or low-oxygen water. The lungs are underdeveloped compared to those of land-dwelling salamanders. They cannot meet the animal’s oxygen demand on their own. An axolotl relying only on lung breathing builds up carbon dioxide faster than it can expel it. Oxygen intake also falls below the level needed for cellular function.
The three pathways work together in water. Remove the water, and two of the three fail immediately. The remaining one, lung breathing, cannot compensate. The water parameters guide covers the dissolved-oxygen targets that keep all three pathways working efficiently, and the temperature guide covers the cool-water requirement that supports oxygen solubility.
What happens to an axolotl’s body when it leaves water?
Within the first minutes out of water, an axolotl’s mucus layer thins and the gill filaments collapse and dry. Between 5 and 15 minutes, the skin starts to dehydrate and the slime coat degrades. Beyond 15 minutes, gill damage may not fully reverse. Survival beyond approximately one hour under typical room conditions is unlikely.
The damage progresses in observable phases. The table below summarises what happens at each interval based on aggregated keeper-community observation and the underlying physiology.
| Time exposed | Skin and mucus | Gills | Respiration | Stress and organ load |
|---|---|---|---|---|
| 1-5 minutes | Mucus layer begins thinning | Filaments collapse and start drying | Cutaneous and gill pathways drop sharply | Cortisol rises; behavioral agitation begins |
| 5-15 minutes | Slime coat degrades; infection risk on return to water | Cellular drying damage starts | Carbon dioxide buildup begins; respiratory acidosis | Stress-hormone load increases |
| 15-60 minutes | Skin dehydration progresses; osmoregulation impaired | Gill damage may be irreversible | Lung-only respiration is insufficient for metabolic demand | Liver, kidney, and nervous-system stress compound |
| Beyond 60 minutes | Severe dehydration | Multiple-pathway failure | Respiratory failure | Survival unlikely under typical room conditions |
The upper-bound window is approximate. Under optimal conditions (high ambient humidity, cool temperatures, the animal resting on a wet surface), some axolotls may survive air exposure approaching one hour. Under typical room conditions with moderate humidity and standard room temperature, the window is shorter. The combination of respiratory failure, skin dehydration, and organ stress is what ultimately kills the animal.
From reviewing common emergency questions across axolotl-keeper rescue networks, the jumped-from-tank scenario is the single most frequent out-of-water emergency. The time between the jump and discovery is the variable that determines whether the animal recovers. Found within a few minutes, returned to dechlorinated temperature-matched water, and most animals recover. Found after an hour or more, gill damage and secondary infection risk often outpace home recovery. Tank lids matter more than emergency response, and the ammonia burn guide covers the clinical injury that can follow secondary infection after air exposure.
What does post-exposure recovery look like in practice?
An axolotl returned to water after brief air exposure may show altered posture for several hours to a day. Common signs include gill clamping, hovering near the surface, or hiding beyond normal patterns. Appetite often drops for 24 to 48 hours. The animal’s slime coat regenerates over days. The primary monitoring window is 48 hours. Watch for white fuzzy patches on the skin or gills (early fungal or bacterial infection). Watch for continued lethargy beyond the first day. Refused food beyond 48 hours and darkened coloration are also warning signs. Any of these warrants veterinary evaluation. The health red flags guide covers the post-exposure symptom catalog, and the cloudy water fix guide covers the bacterial-bloom diagnostic that can appear when an infection takes hold.
Why can’t axolotls walk like other salamanders?
Axolotls cannot walk like terrestrial salamanders because they never undergo the metamorphic transition that restructures the body for land. Their limbs are designed for pushing off underwater substrate, not supporting body weight against gravity. Their skin remains permeable, their gills remain exposed, and their lungs remain underdeveloped throughout adult life.
The comparison to tiger salamanders, spotted salamanders, and other Ambystoma genus members is misleading. Those species do undergo metamorphosis as part of their normal life cycle. The table below summarises the body-plan differences.
| Body system | Metamorphic salamander adult (e.g. tiger salamander) | Neotenic axolotl adult |
|---|---|---|
| Gills | Resorbed during metamorphosis | Retained externally for life as feathery filaments |
| Skin | Thickens and becomes less permeable to reduce water loss | Remains thin and permeable for cutaneous respiration |
| Lungs | Develop fully; primary respiration on land | Remain underdeveloped; supplemental pathway only |
| Limbs | Musculature strengthens for weight-bearing terrestrial locomotion | Designed for pushing off substrate underwater |
| Tail | Tail fin narrows or is lost | Tail fin retained for swimming |
| Lifestyle | Aquatic larva then terrestrial adult | Permanently aquatic; never leaves water |
Axolotls skip every row in the right-hand column. Their limbs are structured for aquatic locomotion (gripping and pushing off underwater surfaces) rather than supporting their full body weight against gravity. Wikipedia frames the broader picture. Unlike most salamander species, axolotls retain their external gills when they mature into adulthood (source: Wikipedia). An axolotl placed on a dry surface does not walk. It drags itself awkwardly, if it moves at all, because its musculoskeletal system was never designed for terrestrial locomotion.
The “Mexican walking fish” label is a misnomer on two counts. Axolotls are not fish (they are amphibians) and they do not walk in any terrestrial sense. They walk along the bottom of their tank using their legs to grip and push off surfaces underwater, where buoyancy supports their body weight. On land, that buoyant support disappears. The axolotls as pets guide covers the keeper-readiness implications of obligate aquatic biology in more detail.
Forced metamorphosis: what it is and why it should not be attempted
Forced metamorphosis is technically possible through administered thyroid hormone or iodine. The procedure produces an animal with a drastically reduced lifespan. It also suppresses immune function and leaves the animal with organs not adapted for sustained terrestrial life. The procedure has significant mortality during the transition. No veterinary or keeper organization recommends it for pet axolotls.
The biology behind the possibility is well established. The Frontiers in Endocrinology review confirms that the axolotl is capable of initiating and completing metamorphosis when thyroid hormone and other endocrine factors of the HPT axis are administered (per Frontiers in Endocrinology, Crowner et al. 2019). The axolotl’s failure to metamorphose naturally is hormonal, not genetic. The tissues retain the capacity to respond to thyroid hormone if it is delivered exogenously.
Researchers have demonstrated this experimentally for decades. A PubMed-indexed 2015 study titled “Thyroxine-induced metamorphosis in the axolotl” (Coots and Seifert) presents a validated method. The protocol induces metamorphosis in adult axolotls with high survivability. The resulting terrestrial animals can be maintained in long-term captivity (source: PubMed Coots and Seifert 2015). The Wikipedia summary records broader research practice. Metamorphosis is reliably induced by administering thyroid hormones, including thyroxine, triiodo-L-thyronine, or thyroid-stimulating hormones (per Wikipedia). Lugol’s solution, which contains both iodide and elemental iodine, also triggers metamorphosis when injected.
These results matter for research. They do not justify the procedure for pet axolotls. The outcome is harmful.
Shortened lifespan and organ stress
A healthy neotenic axolotl in proper captive conditions typically lives 10 to 15 years. A metamorphosed axolotl typically survives only 1 to 5 years after the transformation. That reduction is not a small trade-off. Forced metamorphosis effectively cuts the animal’s expected life by half to ninety percent. The figures here come from keeper- and research-community observation. They do not come from a single peer-reviewed lifespan study. Long-term comparative survival data for forced-metamorphosis pets is sparse.
The organ-stress reasoning is straightforward. The axolotl’s internal organs developed in and for an aquatic environment. The heart is a three-chambered amphibian structure (two atria, one ventricle) designed for mixed oxygenated and deoxygenated blood circulation at the lower metabolic demand of aquatic life. Forcing a terrestrial transition raises the demands on the cardiac, renal, and respiratory systems beyond what those organs evolved to sustain long-term.
Immune suppression during the transition
Metamorphosis itself is immunologically taxing. During and immediately after the transformation, the axolotl’s immune system is compromised. Susceptibility to bacterial and fungal infections rises sharply. A meaningful fraction of animals die during the transition itself rather than after it. Even laboratory protocols with controlled conditions and veterinary oversight report mortality during induction.
Welfare consensus across the husbandry community
No reputable veterinary or keeper organization recommends forced metamorphosis for pet axolotls. The procedure does not produce a healthy terrestrial pet. It produces a stressed, immunocompromised animal with a fraction of its normal lifespan. Vet-tech teams who have encountered metamorphosed axolotls brought in by hobbyists consistently describe the same pattern. The owner wanted a “land axolotl,” administered iodine or thyroxine without veterinary supervision, and arrived at the clinic with a critically ill animal weeks later. The procedure is documented in scientific literature for research purposes. It is not a husbandry recommendation.
Accidental metamorphosis triggers
In rare cases, metamorphosis can begin without the keeper’s intent. High iodine concentrations in tap water are one trigger. Some water conditioners or contaminated sources carry enough iodine to start the process. Exposure to thyroid-disrupting compounds also acts as a partial trigger. Signs include gill resorption, skin texture changes, and altered breathing patterns. If you observe these changes, consult an exotic veterinarian immediately. Do not attempt to complete or reverse the process without professional guidance. The health red flags guide covers when veterinary escalation is appropriate.
How do you safely handle an axolotl out of water during tank maintenance?
Run brief out-of-water handling using a container-not-hands default. Limit exposure to under 1 to 2 minutes per event. Wet your hands with dechlorinated water if hand-handling is unavoidable. Temperature-match any holding water to the main tank. Use a tight-fitting lid to prevent jumps. Return the animal to the tank as quickly as the maintenance task allows.
Brief land exposure is sometimes unavoidable. Several maintenance tasks require moving the axolotl out of its primary tank. Water changes, tank cleaning, and medical examinations are the most common. Emergency transfers also apply during a power outage, a tank leak, or a contamination event. The goal is to minimize air exposure time and maintain skin moisture throughout. The five rules below cover the protocol.
Use a container, not your hands, as the default transfer method
Scoop the axolotl into a clean container filled with tank water. A plastic tub, a large measuring cup, or a clean bucket all work. The animal stays submerged during the transfer. Hand-netting is acceptable with a soft, fine-mesh net. Bare-hand handling strips the protective mucus coat and should be reserved for situations where a container is genuinely impractical. Vet-tech teams review intake animals from inexperienced keepers regularly. They consistently report the same pattern. Bare-hand handling without wetting the hands first opens the door to skin infections. Those infections can take weeks to clear. The intake protocol across most axolotl rescues defaults to soft-mesh net or container transfer. Bare-hand contact is reserved for situations where a container is genuinely impractical.
Keep out-of-water time under 1 to 2 minutes
Sometimes you must briefly hold or position the axolotl in air. Common reasons include a medical check, photographing a possible injury, measuring length, or removing it from a net. Keep any such exposure under two minutes. Wet your hands with dechlorinated water first. Work quickly and return the animal to water as soon as possible. Even within the two-minute window, the mucus layer begins thinning and the gills begin to dry. The shorter the exposure, the less recovery the animal needs afterward.
Temperature-match the holding water
The transfer container’s water should match the main tank temperature within 1 to 2 degrees Fahrenheit. A temperature shock during an already stressful transfer compounds the physiological damage. If the main tank is being fully drained for cleaning, prepare the holding container with temperature-matched, dechlorinated water before you begin. The temperature guide covers the underlying cool-water requirement. The water change schedule covers a related standard practice. For any major-volume change, scoop the axolotl into a temporary container of clean dechlorinated temperature-matched water.
Dechlorinate the holding-container water before adding the animal
Tap water carries chlorine or chloramine. Axolotl.org’s captive requirements page is explicit on this. Every time you change water using tap water, treat it first for chlorine and chloramines (source: Axolotl.org captive requirements). The rule applies to any water the animal will sit in, including transfer containers. Standard dechlorinators (Seachem Prime, API Tap Water Conditioner, Tetra AquaSafe) neutralize both chlorine and chloramine. The water change schedule covers the dechlorinator-handling SOP.
Secure your tank with a tight-fitting lid
Prevention matters more than emergency response. Axolotls jump, particularly in shallow water, during feeding excitement, or when stressed by poor water quality. A glass or acrylic lid with no openings larger than a few millimeters is the standard recommendation. Weight the lid if the axolotl is large enough to push a lightweight cover aside. Check the lid after every filter or heater installation, because cords and tubing create gaps near the rim that animals can slip through. The tank setup guide covers lid specifications and minimum enclosure dimensions.
If you find your axolotl out of the tank
Assess the animal’s condition first. If the skin is still visibly moist and the gills are not fully dried, gently scoop it up with wet hands (dechlorinated water) and return it to the tank. Do not rinse it under running tap water. Chlorine is toxic to amphibian skin already compromised by air exposure. Monitor for the next 24 to 48 hours for signs of secondary infection: white fuzzy patches on the skin or gills, lethargy beyond normal resting, loss of appetite, darkened coloration. If the gills appear dry and matted, if the skin is visibly cracked, or if the animal is unresponsive, return it to water and contact an exotic veterinarian. Extended air-exposure damage opens the door to fungal and bacterial infections that often require veterinary treatment. The ammonia burn guide and cloudy water fix guide cover post-exposure monitoring and the diagnostic flow when infection appears. The within-cluster sibling water testing guide covers the test-kit protocol that catches the water-quality root causes (high ammonia, high temperature, low oxygen) behind the surface-gulping and jumping behavior in the first place.
Are axolotls amphibians or fish, and where does the confusion come from?
Axolotls are amphibians, not fish, despite the “Mexican walking fish” label. They belong to the salamander family Ambystomatidae. The label is a misnomer that misleads new keepers into thinking axolotls are amphibious or paludarium-compatible. Axolotl enclosures must be fully aquatic with no accessible dry surfaces above the waterline.
The “Mexican walking fish” framing came from early European observers who saw the gilled aquatic body and assumed fish biology. It stuck in popular culture even after the animal was correctly classified as an amphibian. The confusion has practical consequences. New keepers who hear “amphibian” think frog or salamander, both of which include terrestrial phases. They then ask three common questions. Do axolotls need a basking area? Can they climb out? Is a paludarium with a shallow water section and a land platform appropriate? The answer to all three is no.
A paludarium is an enclosure with both a water section and an exposed land section. Frogs, newts, fire-bellied toads, and some salamander species use paludariums correctly. Axolotls do not. The drowning-in-reverse risk applies the same way described above. The axolotl may climb onto land during a stress response. It may become unable or unwilling to return to water. The progressive gill collapse and dehydration then follow. Even a shallow paludarium with mostly water and a small land patch creates this risk.
The correct enclosure is a fully aquatic tank with no accessible dry surfaces above the waterline. Water depth should be at least 12 inches (30 centimeters) for an adult. The lid should sit flush with the tank rim so the animal cannot reach an exposed edge or push itself out at the surface. The tank size guide covers volume-per-axolotl rules, and the axolotl care guide hub covers the broader fully-aquatic husbandry framework that follows from the obligate-aquatic biology.
A handful of amphibian species can delay or skip metamorphosis under certain environmental conditions (facultative neoteny), but the axolotl’s neoteny is obligate. Under natural conditions, it never metamorphoses. The PetMD reference reviewed by Sean Perry DVM frames the practical husbandry consequence. Although an axolotl can come out of the water for short periods, they do not live or eat on land (source: PetMD reviewed by Sean Perry DVM). The same reference notes that axolotls live in the water throughout their lives. Treating an axolotl as a paludarium animal contradicts both observations.
Common out-of-water mistakes
The five most common out-of-water mistakes share a pattern. Bare-hand handling without wet hands strips the mucus coat. Adding a dry perch in the tank creates a drowning-in-reverse risk. Rinsing the axolotl with tap water burns gills already stressed by air exposure. Forced-metamorphosis attempts produce a sick animal with a short life. Skipping 48-hour post-exposure monitoring misses secondary infections.
Bare-hand handling without wetting your hands first
The mucus coat on axolotl skin protects against waterborne bacteria, fungi, and parasites. Dry human hands strip that protective layer through contact. If you must handle the animal directly, wet your hands first in dechlorinated tank or treated water. The wet contact still strips some mucus but preserves the protective barrier far better than dry contact. Default to a soft-mesh net or container transfer wherever possible.
Adding a dry perch, platform, or floating decoration
Some keepers add cork bark, floating ledges, or platforms intended to provide variety in the tank. For axolotls these features create a drowning-in-reverse risk. An animal that climbs onto a dry surface during a stress response (high ammonia, temperature spike, poor oxygen) cannot easily return to water. The tank’s interior should have no surfaces above the waterline that the animal can reach.
Rinsing the axolotl with running tap water
A keeper who finds the axolotl out of the tank may instinctively rinse it under the kitchen tap to “freshen” the skin. Tap water carries chlorine and chloramine at concentrations designed to kill bacteria. The same concentration burns amphibian gill tissue, particularly gill tissue already drying and damaged by air exposure. Axolotl.org’s captive requirements reinforce the rule. Every time you change water using tap water, treat it first for chlorine and chloramines (per Axolotl.org captive requirements). The correct response is to return the animal directly to dechlorinated tank water. If the tank itself is the cause of the jump, use temperature-matched dechlorinated water in a clean container instead.
Attempting DIY forced metamorphosis with iodine or thyroxine
The “land axolotl” idea circulates in some hobbyist forums. The procedure is documented in scientific literature, but the keeper-version (dosing iodine or thyroxine without veterinary supervision) typically produces a critically ill animal. The lifespan reduction, immune suppression, and organ-stress consequences are documented earlier in this guide. No reputable veterinary or keeper organization recommends the procedure as a husbandry option.
Assuming recovery is immediate and skipping the 48-hour monitoring window
An axolotl returned to water after brief air exposure may look fine within minutes. Secondary infections often appear 24 to 72 hours later. White fuzzy patches (early fungal growth), darkened coloration, refused food, and lethargy beyond the first day are all warning signs. Monitor the animal closely for 48 hours after any meaningful air-exposure event. The health red flags guide referenced earlier covers the full symptom catalog.
Frequently asked questions
How long can an axolotl survive out of water?
Under optimal conditions (high ambient humidity, cool ambient temperature, resting on a wet surface), an axolotl may survive air exposure approaching one hour. Under typical room conditions, the window is shorter. Gill damage and skin dehydration begin within the first 5 minutes. Irreversible organ stress sets in well before the one-hour mark. Treat any out-of-water exposure as an emergency, not a tolerance test. The animal that survives is not the animal that recovers fully without intervention.
Can axolotls breathe air with their lungs?
Axolotls have rudimentary lungs and can gulp air at the water surface. The lungs are underdeveloped compared to those of terrestrial salamanders and cannot sustain the animal’s full oxygen needs. Lung breathing supplements cutaneous (skin) and gill respiration in water but cannot replace them in air. An axolotl relying only on lung breathing will accumulate carbon dioxide and suffer oxygen deprivation within minutes. Frequent surface gulping in a normally cool tank often signals a water-quality problem that the water testing guide covers diagnostically.
Do axolotls ever leave the water voluntarily?
No. Healthy axolotls do not attempt to leave the water. An axolotl repeatedly found at the surface may be gulping air or pushing against the lid. Both behaviors signal a water-quality problem. Neither is a preference for land. Test ammonia, nitrite, nitrate, pH, and temperature immediately. Common root causes include elevated ammonia, temperature above 68 degrees Fahrenheit, and low dissolved oxygen. Surface behavior is a symptom rather than a behavioral preference, and the test panel that catches the underlying water-quality cause is the same one the water testing guide covers above.
Is a paludarium safe for axolotls?
No. Axolotls require a fully aquatic tank with no exposed land areas. A paludarium with a land section creates a drowning-in-reverse risk. The axolotl may climb onto the land in a stress response. It may then be unable or unwilling to return to water. Progressive gill collapse and dehydration follow. Axolotl enclosures should have water depth of at least 12 inches with no accessible dry surfaces above the waterline. The tank setup guide covers correct enclosure specifications.
My axolotl jumped out of the tank. What do I do?
Gently scoop the axolotl up with wet hands (wet with dechlorinated water) and return it to the tank immediately. Do not rinse it under running tap water. Chlorine and chloramine burn amphibian gills, particularly gills already drying from air exposure. Monitor closely for 48 hours for signs of secondary infection: white fuzzy patches on the skin or gills, loss of appetite, lethargy, or darkened coloration. If the animal was out of water for more than a few minutes or shows gill damage (matted, discolored, or curled filaments), consult an exotic veterinarian.
