What Do Toads Eat in Captivity
In captivity, toads thrive on a diet of live, appropriately sized invertebrates that mimic their natural prey, primarily consisting of insects such as crickets, mealworms, earthworms, and occasional roaches or waxworms. Toads are carnivorous ambush hunters, so all food must be alive and move to trigger feeding responses. Juveniles typically require daily meals of small prey, while adults often do well with feedings two to three times per week, though this varies by species, age, and condition. Offering variety and ensuring proper calcium and vitamin D3 supplementation is essential to prevent metabolic bone disease and support overall health.
Prey Options Captive Toads Will Accept
Toads generally accept a rotating menu of gut-loaded insects and occasional invertebrates. Choosing the right prey size is critical: the prey should be no wider than the toad’s head to avoid choking or impaction. Below is a practical overview of common prey types, relative value, and appropriate sizing by toad size.
| Prey Type | Best For | Notes and Frequency |
|---|---|---|
| Crickets | Juveniles and staple feeding | Good all-around option; choose sizes to match toad head width |
| Earthworms (red wigglers, nightcrawlers) | All ages; excellent nutrition | High moisture; use as a staple or treat depending on species |
| Mealworms | Occasional treat for adults | Higher fat, lower calcium; dust with supplement and limit frequency |
| Roaches (e.g., Dubia, discoid) | Adults; efficient nutrition | Leaner than mealworms; good staple when appropriately gut-loaded |
| Waxworms | Rare treat only | Very high fat; overuse can lead to obesity and nutrient imbalances |
| Black soldier fly larvae (Phoenix worms) | All ages | Good calcium-to-phosphorus balance; useful as staple or treat |
Prey Size Guidelines
Always select prey no larger than the width of the toad’s head. For small toadlets, pinhead crickets and micro-eworms are appropriate; for medium toads, use standard crickets and small earthworms; for large adults, offer adult crickets, large earthworms, and occasional roaches. Avoid overly large or irregularly shaped prey that can cause impaction or injury.
Feeding Frequency and Amount
Young, growing toads need more frequent meals, while adults do well on a reduced schedule. Observe body condition and adjust as needed. The goal is a toad that is plump but not rounded, with visible structure but no prominent spine.
- Juveniles and toadlets: Feed daily or every other day with small, appropriately sized prey.
- Sub-adults (approx. 2–5 cm snout-to-vent): Feed every 2–3 days with medium prey such as adult crickets or small earthworms.
- Adults (5 cm+): Offer food 2–4 times per week for most terrestrial species; some may accept meals every 7–10 days during cooler months.
Supplementation and Nutrition Balance
Dust prey items with a high-quality amphibian multivitamin and calcium to prevent deficiencies. A standard schedule is to dust food lightly with calcium containing vitamin D3 every feeding for juveniles, and every second or third feeding for adults. Use a separate calcium without D3 in UVB-equipped setups if the animal receives adequate UVB exposure. Rotate prey types to promote nutritional variety and reduce the risk of selective feeding.
Hydration and Feeding Practices
Toads obtain much of their water through their skin and from prey, but a shallow, clean water dish should always be available. Aim for dechlorinated water changed daily. During feeding, offer prey in the evening or at night when many toad species are most active. Hand-feed with tweezers when necessary, and remove uneaten prey within 12–24 hours to maintain hygiene and prevent pests. Observe your toad’s body condition regularly and adjust portion sizes to avoid underfeeding or overfeeding.
Safety Considerations and Troubleshooting
Only offer live prey; dead or freeze-dried insects rarely trigger feeding responses and lack the moisture content of live food. Avoid feeding wild-caught insects due to potential pesticide exposure. Do not feed mealworms as a staple for smaller or juvenile toads, as their hard exoskeleton can cause impaction. If your toad refuses food consistently, check enclosure temperature, humidity, hiding spots, and consult an experienced amphibian veterinarian to rule out illness or environmental stress.
