Earthworms are the nutritionally superior staple food for captive axolotls. Pellets are useful backup for situations where worms are impractical. The optimal approach for most keepers is a rotation: earthworms primary two to three times per week, quality sinking pellets filling specific gaps, occasional treats for variety. Cost and convenience trade-offs are real; nutrition and enrichment trade-offs are too.
The nutritional comparison: how earthworm and pellet nutrition compare for axolotls
Earthworms are nutritionally superior to pellets. Per AxolotlCentral, earthworms and night crawlers contain over 60 percent protein and a Ca:P ratio greater than 1 (source: AxolotlCentral care guide). Pellets typically contain 40 to 46 percent protein and 10 to 20 percent fat. Earthworms also provide natural moisture, micronutrient diversity, and soft body texture.
The nutritional-comparison table maps each macronutrient and feeder-quality dimension to its nightcrawler and pellet baselines. The practical nutritional gap shows up most clearly in long-term body condition. Axolotls fed primarily on earthworms tend to develop fuller gill filaments with brighter coloration and maintain leaner body condition compared to axolotls raised predominantly on pellets. This is a widely observed pattern in keeper communities, hobbyist forums, and rescue intake records.
| Nutrient | Nightcrawler (whole) | Soft pellet (typical) |
|---|---|---|
| Protein (dry weight) | Above 60 percent | 40 to 46 percent |
| Fat | 5 to 10 percent | 10 to 20 percent |
| Calcium:phosphorus ratio | Above 1:1 | Variable by brand |
| Moisture | High (natural) | Low (requires rehydration in water) |
| Fiber and gut content | Natural gut content | Binder-dependent |
| Micronutrient diversity | Broad (Ca, Fe, Zn, P, Mn) | Supplemented, narrower |
| Impaction risk | Negligible (soft body) | Low (if soft-formula) |
The axolotl care guide covers the husbandry framework that the feeding decisions sit inside. The axolotl feeding schedule by age guide covers feeding frequency by age. The axolotl vitamin supplement guide covers the supplementation decision that sits alongside the feeder-selection decision. The what do axolotls eat guide covers the broader diet overview including non-staple food types.
Protein and fat
Earthworms carry the protein content axolotls need without the fat overhead of pellets. Per AxolotlCentral, earthworms and night crawlers meet the nutritional requirements of your axolotl better than any other option, as they contain over 60 percent protein and a Ca:P ratio greater than 1 (per AxolotlCentral care guide). Pellets typically run 40 to 46 percent protein and 10 to 20 percent fat. The lower protein and higher fat profile is acceptable for occasional feeding but produces fattier body condition over months if pellets dominate the rotation. Pellet protein comes from fish meal, shrimp meal, or other rendered animal sources rather than whole prey.
Calcium and phosphorus
Calcium-to-phosphorus ratio matters for axolotl skeletal health. Per AxolotlCentral, earthworms have a Ca:P ratio greater than 1, which supports natural calcium balance without separate supplementation (per AxolotlCentral care guide). The 2:1 calcium-to-phosphorus ratio commonly cited for amphibian husbandry is naturally met by earthworms. This is why insect-based diet protocols that require calcium dusting do not apply to axolotls. Pellet brands vary widely in their calcium content, and a pellet-dominant diet can drift toward calcium insufficiency over time depending on the formulation.
Micronutrient diversity and moisture
Earthworms provide trace minerals including calcium, iron, zinc, phosphorus, and manganese that contribute to skeletal integrity and metabolic processes. They also carry natural moisture content that aids digestion and a soft body texture that passes through the axolotl’s suction-feeding gut without impaction risk. Pellets are formulated to approximate the nutritional needs of carnivorous aquatic species but are processed food with inherent tradeoffs. They lack natural moisture, fiber diversity, and micronutrient breadth compared to whole prey. The amino acid profile in earthworms includes the full range axolotls need for tissue repair, gill regeneration, and immune function.
Nightcrawlers vs red wigglers: which earthworm to use
Nightcrawlers (Lumbricus terrestris) are the standard recommendation. They are large enough to constitute a full adult meal, carry high protein content, and axolotls accept them readily. Red wigglers (Eisenia fetida) are smaller, carry lower protein content per Liberty Land Rescue, and produce a bitter defensive slime when stressed. Nightcrawlers remain the preferred species for most keepers.
The earthworm-species table maps the two most common feeder worms to their main differences. Not all earthworms are interchangeable. The two species most commonly available to axolotl keepers differ in size, protein content, palatability, and culture difficulty. Selecting the right species matters more than keepers initially assume.
| Dimension | Nightcrawler (Lumbricus terrestris) | Red wiggler (Eisenia fetida) |
|---|---|---|
| Typical protein content | Above 60 percent dry weight | Approximately 11 percent wet-weight basis with around 2 percent fat |
| Typical moisture content | Moderate | Approximately 84 percent moisture |
| Size | Large; single worm can feed adult axolotl | Small to medium; multiple worms needed for adult portion |
| Palatability | High; axolotls accept readily | Lower; bitter defensive slime when stressed triggers rejection |
| Sourcing | Bait shops, pet stores, online, home culture | Standard worm composting bin; easier home culture |
| Best use | Adult primary staple; juveniles need cut segments | Juvenile feeding (smaller size); secondary option |
Per Liberty Land Axolotl Rescue, red wiggler crude protein content runs around 11 percent on a wet-weight basis with approximately 2 percent fat and 84 percent moisture (source: Liberty Land Axolotl Rescue red wigglers article). The significant practical problem with red wigglers is their defense mechanism. When stressed or handled, they produce a bitter-tasting slime that causes many axolotls to gag, spit out the worm, or refuse it entirely. Some keepers address this by blanching the worm briefly under hot water and then rinsing with cold water to strip the mucus coating, but blanched worms are dead and some axolotls refuse non-moving food.
Red wigglers do have one practical advantage. Their smaller size makes them suitable for juvenile and sub-adult axolotls without cutting, and they are easier to culture at home in a standard worm composting bin at room temperature. However, because you typically need to offer 3 to 5 red wigglers to match the caloric content of a single nightcrawler, and because the rejection rate from the bitter mucus is significant, nightcrawlers remain the preferred species for most keepers. The axolotl live food safety guide covers the full per-feeder safety dimension for both species.
Long-time hobbyist breeders feeding multi-axolotl colonies consistently observe that the single most reliable predictor of strong gill coloration and healthy body condition in adult axolotls is consistent nightcrawler feeding. The most common dietary correction recommended when new keepers report dull gills or slow growth is switching from pellet-only or red-wiggler-only diets to nightcrawler-primary feeding. The pattern holds across decades of axolotl-keeping practice.
When pellets are the better choice
Pellets serve specific roles where worms are impractical. They work for travel and vacation feeding with a pet sitter. They bridge juvenile transitions when the animal is too small for whole worms. They cover seasonal supply gaps. They reduce cost for multi-axolotl setups. Pellets are not inferior food; they are different food.
| Pellet advantage | When it matters | Trade-off | Cross-link |
|---|---|---|---|
| Shelf-stable storage | Long-term household stockpile, travel | No enrichment value | art12 what-do-axolotls-eat |
| Controlled portion measurement | Sitter-managed feeding during travel | Refusal risk if axolotl never habituated | art47 refusing-food |
| Balanced macros from formulation | Multi-axolotl cost management | Brand variability | art48 vitamin-supplement-guide |
| Travel and vacation convenience | Trips 3 days to 2 weeks with pet sitter | Pet sitter overfeed risk if uneaten not removed | art14 cloudy-water-fix |
Travel and vacation feeding
When you leave your axolotl in the care of a pet sitter or family member, pellets are far easier to manage than live worms. A sitter can drop a measured number of pellets into the tank without needing to handle, store, or cut live worms. For trips lasting a few days to two weeks, pellets with clear written instructions eliminate the most common sitter errors: overfeeding, leaving uneaten worms to decompose, and incorrect worm storage leading to dead worms in the refrigerator. The axolotl cleaning routine covers the uneaten-food removal protocol that sitters should follow.
Picky juvenile transition
Some juvenile axolotls between 1 and 3 inches refuse cut earthworm segments but accept soft pellets in the 3 mm size range. The pellet’s uniform shape and sinking motion can trigger the feeding response in juveniles that are not yet large enough or experienced enough to strike at worm segments. Using pellets as a bridge food during this stage is preferable to underfeeding. As the juvenile grows and its feeding confidence increases, gradually introduce small worm segments alongside the pellets to transition toward an earthworm-primary diet. The axolotl size and growth guide covers the growth-checkpoint feeder transitions.
Supply gaps
Nightcrawler availability varies by season and location. In winter, bait shops may run low. Online suppliers occasionally have shipping delays or temperature-related mortality in transit. Keeping a bag of quality pellets in the pantry ensures your axolotl never misses a meal because of a supply interruption. For keepers who do not culture their own worms, pellets function as essential dietary insurance. The axolotl refusing food guide covers what to do if the axolotl rejects pellets when worms run out.
Cost management for multi-axolotl setups
A keeper housing four or five adult axolotls goes through nightcrawlers quickly. Supplementing two or three worm meals per week with one pellet meal reduces the ongoing earthworm expense without meaningfully compromising nutrition, provided worms remain the primary food. The axolotls tank mates guide covers the cohabitation framework for multi-axolotl setups including the feeding-competition consideration.
Selecting the right pellet
The right pellet matters. Select soft sinking pellets with at least 40 percent protein and less than 10 percent fat, with no artificial dyes or fillers. Hard tropical-fish pellets are not appropriate; they do not soften quickly enough and can cause digestive issues when swallowed whole.
The pellet-brand guidance table maps the most widely-discussed brands in the axolotl keeper community to their specifications and use cases. Brand-name references should be verified at purchase point because formulations change over time. The table is brand-agnostic in approach: the underlying specs matter more than the brand label.
| Pellet category | Examples | Specs | Use case |
|---|---|---|---|
| Soft sinking carnivore | Hikari Sinking Carnivore, Invert Aquatics soft pellets | Above 40 percent protein, below 10 percent fat, soft formulation, sinks within seconds | Adult staple secondary food |
| Aquatic carnivore formulation | Repashy Grub Pie (gel formula), Northfin Veggie Pellet (avoid as staple) | Variable; check label per batch | Treat or supplement use |
| Soft salmon pellet (colony setting) | Per Axolotl.org/feeding documentation | Approximately 45 percent protein and 20 percent fat per Axolotl.org/feeding verbatim | Reference for colony-scale husbandry |
| Pellet size 3 mm | Juvenile-appropriate sizing | 3 mm size per Axolotl.org/feeding | Juveniles under 6 inches |
| Pellet size 5 mm | Adult-appropriate sizing | 5 mm size per Axolotl.org/feeding | Adults over 6 inches |
Look for soft pellets
Hard tropical-fish pellets do not soften quickly enough and can cause digestive issues when swallowed whole. Soft sinking pellets dissolve gradually after entering the stomach and pose minimal impaction risk. The texture matters because axolotls feed via suction and swallow food whole rather than chewing. The pellet must be small enough to swallow comfortably and soft enough to pass through the digestive tract without obstruction.
Protein and fat specifications
Per Axolotl.org/feeding documentation, soft salmon pellets with approximately 45 percent protein and 20 percent fat produced good growth results in axolotl colony settings, and pellet size should be 3 mm for juveniles and 5 mm for adults (source: Axolotl.org feeding). For non-colony household feeding, target above 40 percent protein and below 10 percent fat where possible to keep body condition lean. The 20 percent fat colony figure reflects a documented growth-focused regime; for adult maintenance feeding, lower fat percentages reduce the risk of body-condition issues.
Size by age
Per Axolotl.org/feeding, pellet size should be 3 mm for juveniles and 5 mm for adults (per Axolotl.org feeding). Pellets too large for the axolotl will be ignored or spit out. Pellets too small for an adult may not trigger the feeding response, which depends on movement and scent detection more than visual cues. Match pellet size to body size, not to convenience.
Warning signs
Avoid pellets with artificial dyes, excessive fillers, or “all-in-one” marketing claims that suggest medication or treatment additives. The axolotl vitamin supplement guide covers the do-not-confuse-supplementation-with-medication framework. Pellets that smell rancid, show discoloration, or have expired should be discarded. Storage matters: pellets stored in humid conditions lose appeal and may develop mold.
Feeding response and enrichment value compared
Earthworms trigger a strong natural predatory response. A worm dropped into the tank or held with feeding tongs moves, wriggles, and releases chemical cues that axolotls detect through their lateral line and olfactory receptors. Pellets sit motionless on the substrate and offer no enrichment value beyond basic caloric delivery. Young axolotls especially depend on movement as a feeding trigger.
The strike-and-suction sequence that follows the keeper presenting a worm is the closest thing to natural foraging behavior a captive axolotl performs. This behavioral activation matters. Axolotls that regularly hunt live or recently killed prey maintain sharper feeding reflexes and show more active exploratory behavior outside feeding times. The behavioral dimension of food choice is real even though it does not show up on a nutritional label.
Predatory response with worms
Earthworms trigger movement-driven and chemical-driven feeding cues that axolotls detect through their lateral line system and olfactory receptors. The behavioral activation includes head-orienting, tracking, and the characteristic suction-feeding strike. Live or tong-held worms that move during presentation reliably elicit feeding response even in axolotls that have been off food for a few days. The axolotl hides and enrichment guide covers the broader environmental enrichment framework that includes feeding-time enrichment as one component.
Pellet passive feeding
Pellets sit motionless on the substrate. Most adults learn to recognize pellets as food by scent alone, but the feeding response is typically slower and less vigorous than with worms. An axolotl eating pellets walks to a stationary object and suctions it up. This is not harmful, but it represents a missed enrichment opportunity compared to worm feeding. Pellet-only diets correlate over months with reduced feeding vigor and slower response to live prey when reintroduced.
Juvenile movement-trigger dependency
Juvenile axolotls under 3 inches especially depend on movement as a feeding trigger. A wiggling worm segment or live blackworm is often the difference between eating and fasting for juveniles. The visual and chemical cues from moving prey activate the feeding reflex in a way that motionless pellets do not. For juveniles, worm-based feeding is functionally important not just preferred. The axolotl stress signs guide covers how feeding-response loss relates to broader stress patterns.
Keeper-community accounts working with surrendered pellet-only axolotls describe a consistent pattern. Animals raised exclusively on pellets for months often show reduced feeding vigor when first offered live food. They require a transition period of tong-feeding and gradual worm introduction before they consistently strike at moving prey. The behavioral dimension of long-term pellet feeding is not always visible day-to-day but compounds over months.
Building a rotation strategy that uses both
The optimal feeding approach is rotation. Earthworms serve as the primary staple two to three times per week. Pellets fill specific gaps. Per Axolotl.org/feeding, even staple foods need variety: bloodworms and blackworms can be fed as a staple, provided that there is a little variety occasionally to offset any imbalance (per Axolotl.org feeding). Adjust ratios by age and preference.
The rotation-strategy by-age table maps each life stage to its recommended worm and pellet frequency. The rotation is flexible. The principle is earthworm-primary with pellets filling gaps, not the reverse. Specific ratios depend on supply, sitter availability, and individual axolotl preferences. The table provides a workable baseline.
| Life stage | Earthworm frequency | Pellet frequency | Notes |
|---|---|---|---|
| Juvenile (2 to 6 inches) | Daily small worm segments | Daily 3 mm pellets on days worm prep is impractical | Alternate; favor whole-prey feeding when possible |
| Subadult (6 to 12 months) | 3 to 4 worm meals per week | 1 to 2 pellet meals per week | Transition toward worm-primary as juveniles grow |
| Adult (7 plus inches) | 2 to 3 worm meals per week | 0 to 1 pellet meals per week | Earthworm staple; pellets as backup |
Standard adult rotation
For adult axolotls over 7 inches, two to three nightcrawler meals per week (one worm per meal), zero to one pellet meals per week (4 to 6 pellets per meal adjusted by size), and one to two rest days per week with no feeding gives the axolotl the nutritional benefits and enrichment of whole-prey feeding on most days with a pellet meal available as a scheduling convenience or when worm supply runs low. The axolotl portion size guide covers detailed portion sizing across all ages and food types.
Juvenile rotation
Juvenile axolotls between 2 and 6 inches need daily feeding alternating between small worm segments and 3 mm pellets. Use pellets on days when worm preparation is impractical or when the juvenile rejects the worm segment. As the juvenile grows past 4 inches, shift toward worm-primary and reduce pellet frequency. The axolotl feeding schedule by age guide covers the full juvenile feeding cadence including portion expectations at each growth checkpoint.
Travel mode
Switch to pellets entirely for the duration of the trip. Pre-measure daily pellet portions in labeled bags or containers. Leave written instructions for the sitter: number of pellets, when to feed, how long to leave food in the tank, when to remove uneaten pellets. Resume worm feeding when you return. The travel transition usually does not disrupt feeding, but if the axolotl refuses the pellets the sitter should not panic; healthy adults tolerate short fasting periods without harm.
When to skip pellets entirely
If you culture your own nightcrawlers or have reliable year-round access, there is no nutritional reason to include pellets in the rotation at all. An earthworm-only diet is nutritionally complete for axolotls at all life stages past the hatchling phase, and the enrichment value of live feeding is a genuine welfare benefit. Keep pellets on hand as emergency backup even if you do not use them regularly. The axolotl obesity guide covers body-condition monitoring that applies equally to worm-fed and pellet-fed axolotls.
When to increase pellet ratio
If your axolotl consistently refuses worms (some individuals are unusually picky), pellets prevent nutritional gaps while you work on worm acceptance. Tong-feeding worm segments, trying different worm species, and feeding at dusk when axolotls are most active can help overcome worm refusal. For troubleshooting persistent food refusal, the axolotl refusing food guide covers the full diagnostic sequence.
Cost and convenience: a realistic comparison
Most keepers choose between worms and pellets based partly on practical logistics. Pellets win on convenience by a wide margin. They have shelf life measured in months, require no refrigeration, no cutting, and no live-organism maintenance. Cost per meal favors pellets for purchased worms; favors home-cultured worms long-term.
| Dimension | Earthworms | Pellets |
|---|---|---|
| Cost per meal (adult) | 25 to 40 cents per worm from bait shop; lower in bulk; lowest from home culture | 5 to 15 cents per meal depending on brand and pellet count |
| Storage | Refrigerator at 40 to 50 degrees Fahrenheit for store-bought; 55 to 65 degrees Fahrenheit for home culture bin | Sealed container at room temperature; shelf life months to years |
| Handling | Refrigerator storage, rinse before feeding, cut for juveniles, hand or tong handling | Open container, measure with spoon, drop in tank |
| Travel mode | Difficult; sitter must store, rinse, cut | Easy; pre-measured portions, written instructions |
Earthworm costs
A dozen nightcrawlers from a bait shop typically costs 3 to 5 USD and feeds a single adult axolotl for approximately two weeks at the standard every-other-day to every-third-day schedule. Online bulk orders reduce the per-worm cost but introduce shipping fees and temperature-dependent mortality risk. Home culturing eliminates the recurring purchase cost after the initial bin setup (roughly 30 to 50 USD for a worm bin, bedding, and starter population), but requires ongoing maintenance: keeping the bin at the right temperature, feeding the worms vegetable scraps, and harvesting periodically.
Pellet costs
A container of quality sinking pellets costs 8 to 15 USD and lasts a single adult axolotl several months when used as a supplement. Even as a sole food source, pellets are significantly cheaper per meal than purchased earthworms. No special storage beyond a sealed container at room temperature is needed. No living organisms to maintain between feedings.
Convenience comparison
Pellets win on convenience by a wide margin. They have a shelf life measured in months, require no refrigeration, no cutting, no handling of live organisms, and no cleanup beyond removing uneaten pellets after 30 minutes. Earthworms require refrigerated storage or a maintained worm bin, rinsing before feeding, cutting for juveniles, and prompt removal of uneaten portions to prevent water quality degradation. For a full discussion of uneaten food removal and tank maintenance, the axolotl cleaning routine guide covers the maintenance framework.
The honest assessment
The convenience advantage of pellets is real and should not be dismissed. Not every keeper has the time, space, or tolerance for worm husbandry. A keeper who feeds pellets consistently and maintains excellent water quality is doing far better by their axolotl than a keeper who buys worms sporadically, lets them die in the refrigerator, and ends up skipping meals. Consistency and water quality matter more than worm-vs-pellet purity. The right answer for any given keeper depends on what they can sustainably maintain.
Food safety considerations for both options
Both worms and pellets carry food-safety considerations. Earthworms from gardens, bait shops, or online suppliers can carry parasites, pesticide residue, or bacterial contamination. Pellets carry lower acute contamination risk but expire and can develop mold. Uneaten pellets degrade water quality within minutes. Source worms from pesticide-free sources, store pellets sealed, and remove uneaten food promptly.
| Feeder type | Primary food-safety concern | Practical response | Cross-link |
|---|---|---|---|
| Earthworms | Parasites, pesticide residue, bacterial contamination | Buy pesticide-free; rinse under cool dechlorinated water; never collect from treated lawns | art45 live-food-safety |
| Pellets | Mold from improper storage; lost nutritional value past expiry | Sealed container; cool dry storage; check expiry date; discard if off-smell | art48 vitamin-supplement-guide |
| Uneaten food (either type) | Water-quality degradation; ammonia spike | Remove uneaten portions within 15 to 30 minutes; test water if recurring | art14 cloudy-water-fix + art20 water-testing-guide |
Worm food safety
Earthworms sourced from gardens, bait shops, or online suppliers can carry parasites, pesticide residue, or bacterial contamination. Buy from pesticide-free sources, rinse worms under cool dechlorinated water before feeding, and never collect worms from treated lawns, roadsides, or agricultural fields. If you culture your own worms, use clean bedding and pesticide-free vegetable scraps. For a complete breakdown of parasite risks, quarantine procedures, and sourcing standards, the axolotl live food safety guide covers the per-feeder safety framework.
Pellet food safety
Pellets carry lower acute contamination risk than live food, but they have their own concerns. Expired or improperly stored pellets can develop mold or lose nutritional value. Check the expiration date, store in a sealed container away from moisture and heat, and discard any pellets that smell off or show discoloration. Uneaten pellets left in the tank for more than 15 to 30 minutes begin to dissolve and degrade water quality. The nitrogen load from decomposing pellets can spike ammonia in tanks with marginal filtration. The axolotl water testing guide covers the parameter testing cadence that catches feeding-related water-quality issues early. The axolotl substrate guide covers bare-bottom and fine-sand substrate options that make uneaten pellet removal practical.
Frequently asked questions
Can I feed my axolotl only pellets and skip worms entirely?
A pellet-only diet is acceptable as a last-resort sole food when worms are genuinely unavailable, but it is nutritionally inferior to an earthworm-primary diet over the long term. Pellets lack the micronutrient diversity, natural moisture content, and favorable calcium-to-phosphorus ratio of whole earthworms (per AxolotlCentral care guide). Axolotls on pellet-only diets miss the enrichment and behavioral stimulation of hunting live prey. If quality pellets contain at least 40 percent protein, the animal will survive and grow. Body-condition monitoring is critical because pellet brands vary widely in fat content. Most keepers have access to nightcrawlers through bait shops, online suppliers, or home culturing, and worm-primary feeding produces healthier long-term outcomes.
Are red wigglers safe for axolotls?
Red wigglers are not toxic to axolotls, but they produce a bitter defensive slime when stressed that causes many axolotls to reject them. Per Liberty Land Axolotl Rescue documentation, red wiggler protein content runs around 11 percent on a wet-weight basis with around 84 percent moisture, which is lower nutritional density than nightcrawlers (per Liberty Land Axolotl Rescue). Some keepers blanch red wigglers under hot water and rinse with cold water to remove the slime, but blanched worms are dead and some axolotls refuse non-moving food. Red wigglers work as a secondary worm option for juveniles benefiting from smaller size, but nightcrawlers remain the preferred earthworm species for most keepers.
How many pellets should I feed per meal?
For an adult axolotl over 7 inches, 4 to 6 soft pellets at 5 mm size per meal is a reasonable starting baseline. Feed as many as the axolotl will eat within 3 to 5 minutes, then remove uneaten pellets to prevent water-quality degradation. Adjust based on body condition. If the axolotl is gaining weight or developing a rounded belly, reduce the count. Juveniles eating 3 mm pellets may take 6 to 10 per meal depending on size. The portion-size guide covers feeding amounts by age and body weight in detail.
Do I need to cut earthworms before feeding?
For adult axolotls over 6 inches, a full-sized nightcrawler can be swallowed whole. For juveniles and sub-adults under 6 inches, cut nightcrawlers into segments no wider than the distance between the axolotl’s eyes using clean scissors. Rinse the cut segments under cool dechlorinated water before offering them. As the axolotl grows, increase segment size gradually until whole worms are accepted. Cutting is a safety measure to prevent choking on pieces too large for the animal to swallow.
How do I store earthworms between feedings?
Keep nightcrawlers in their original bedding or fresh coconut coir inside a ventilated container in the refrigerator at 40 to 50 degrees Fahrenheit. At this temperature, nightcrawlers enter a sluggish state and survive for 2 to 4 weeks with minimal maintenance. Remove any dead worms promptly because decomposing worms contaminate the container. If you culture worms at home, maintain the bin at 55 to 65 degrees Fahrenheit and harvest as needed. Red wigglers do not require refrigeration and can be kept at room temperature in a standard composting bin.
