Tiger salamanders are opportunistic feeders. Healthy, established animals are typically enthusiastic feeders, although appetite can vary with temperature, stress, life stage, and health. This guide covers what to feed, how often, and how to supplement appropriately.
Tiger Salamander Feeding at a Glance
| Adults | Every 2–3 days as a starting framework; adjust for individual and prey type |
| Juveniles | Every 1–2 days as a starting framework |
| Portion size | Enough appropriately sized prey to maintain healthy body condition; adjust for prey type and individual |
| Uneaten prey | Remove within a few hours |
Best Prey Items
Earthworms and Nightcrawlers (Staple)
Earthworms and nightcrawlers are excellent staple prey for tiger salamanders because they provide substantial moisture and useful nutritional variety compared with relying on a single feeder insect. Nightcrawlers are large enough for adult tiger salamanders and can be purchased from bait shops or online feeder suppliers. Worms sourced from gardens or wild areas should be avoided unless you can confirm they haven't been exposed to pesticides or fertilizers.
Dubia Roaches
Dubia roaches are a nutritious, low-odor feeder insect that gut-loads well and is easy to maintain. They are a good rotation item alongside earthworms and provide dietary variety. Use appropriately sized roaches — adults can handle larger roaches, juveniles need smaller ones.
Crickets
Crickets are widely available and accepted by tiger salamanders. Gut-load crickets for 24–48 hours before feeding to improve their nutritional value. Crickets left in the enclosure overnight can stress or injure a salamander, so remove uneaten crickets promptly.
Occasional Variety
Waxworms and hornworms can be offered occasionally as variety. Both are high in fat or water content respectively and shouldn't form a significant part of the regular diet. Black soldier fly larvae (BSFL) are a calcium-rich option worth including in rotation.
Foods to Avoid
- Wild-caught invertebrates — risk of pesticide exposure and parasite introduction
- Feeder fish or rodents — unnecessary as routine captive foods; appropriately sourced invertebrate prey provides better staple options
- Processed or human food — not appropriate for any amphibian
- Fireflies — toxic to amphibians
Supplementation
Supplementation needs vary with prey variety, feeder nutrition, life stage, and the supplements being used. Insect-heavy diets may benefit from appropriate calcium and vitamin supplementation, while a varied diet built around quality earthworms and nightcrawlers reduces reliance on supplementation. Follow the dosing guidance for the specific amphibian-safe supplement being used and avoid excessive supplementation.
How to Feed
Tiger salamanders can be fed directly in their enclosure using feeding tongs, or in a separate feeding container to keep the enclosure clean and reduce substrate ingestion. Tong feeding is straightforward with this species — they respond readily to movement and will strike at prey presented near them. Remove any uneaten prey within a few hours to prevent stress and substrate contamination.
Overfeeding
Tiger salamanders will eat whenever food is offered regardless of hunger. Obesity is a genuine long-term health concern. Stick to a consistent feeding schedule rather than feeding on demand, and monitor body condition — a healthy adult should have a rounded but not visibly bloated abdomen.
