Part of the Salamanders
Terrestrial and semi-aquatic tailed amphibians kept in cool, humid, heavily planted setups. Most are nocturnal, secretive, and best observed rather than handled, with many secreting skin toxins.

Habitat & space requirements
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.
Habitat & enclosure
Adult tiger salamanders are terrestrial burrowers and need a horizontally oriented terrarium with ample floor space, at least a 20-gallon (about 75-liter) long tank for one adult, with more space being better. Provide several inches of deep, moist, diggable substrate such as coconut fiber, organic topsoil, or a bioactive soil-and-leaf-litter mix so they can burrow, along with cork bark hides, leaf litter, and a shallow, easily exited water dish with dechlorinated water that is changed regularly. House adults singly, since they are cannibalistic and may eat or injure a smaller cagemate.
This is a cool, temperate species: keep temperatures around 60-72 F (16-22 C) and avoid sustained heat above the mid-70s F, so many setups need no supplemental heat and may need to be kept in a cooler room in summer. Humidity should stay moderate to high with a consistently damp (not waterlogged) substrate, and bright lighting is unnecessary; UVB is not strictly required but a normal photoperiod helps. Larval and recently metamorphosed animals have different, more aquatic needs.
Substrate
Offer several inches of loose, moist burrowing substrate such as coconut fiber, organic topsoil, or a soil-and-sphagnum mix so these fossorial salamanders can dig and den. Keep it damp but well-drained, and avoid gravel or sand that can cause impaction.
Equipment & setup
Keep terrestrial adults cool at 60-72F (overheating is dangerous, so no basking lamp is needed and the room may need to stay cool) with moderate humidity and a shallow dish of dechlorinated water for soaking. No UVB is required since they are nocturnal burrowers; a secure lid is essential because they are strong, persistent diggers and escape artists.
Diet
Tiger salamanders are voracious carnivores with strong appetites. Feed adults gut-loaded insects and invertebrates such as earthworms (an excellent staple), nightcrawlers, crickets, dubia roaches, and occasional treats; very large adults may take an occasional pinky mouse, though this should be infrequent to avoid obesity and fatty disease. Dust insect feeders with calcium and a multivitamin periodically.
Feed adults two to three times per week and growing juveniles more often, adjusting to maintain a healthy body condition rather than a bloated one. They will readily overeat and become obese, so portion control is important. Many learn to take food from tongs, which reduces accidental substrate ingestion.
Behavior & temperament
Tiger salamanders are secretive and spend much of their time burrowed, emerging to feed, especially after dark or after the substrate is dampened. They are notably food-driven and often become bold beggars at the front of the enclosure once they associate their keeper with feeding. They should be handled minimally and only with clean, wet, fragrance-free hands, since their skin is permeable and easily harmed by oils and residues, and they can deliver a surprisingly firm bite during feeding.
Keep them solitary to prevent cannibalism. Enrichment is environmental: a deep diggable substrate, leaf litter and hides to explore, and varied prey offered in different ways. Legality varies; some U.S. states regulate the collection, sale, or use of tiger salamanders (often because of their use as fishing bait and disease concerns), so keepers should confirm local rules. Note that the closely related western or barred tiger salamander (Ambystoma mavortium), now treated as a separate species, is also common in the trade and has very similar care.
Health
Common problems include obesity and related issues from overfeeding, metabolic bone disease from inadequate calcium, impaction from ingesting loose or oversized substrate during feeding, and bacterial or fungal skin infections from overly wet or dirty enclosures. Heat stress is a real risk for this cool-climate species, and chytrid and ranavirus affect Ambystoma salamanders.
Prevention centers on keeping the enclosure cool and clean, feeding measured portions of a varied dusted diet, avoiding substrate ingestion (tong-feeding or feeding on a dish helps), and quarantining new animals. Bloating, skin sores or discoloration, straining, lethargy, or appetite loss warrant an amphibian-experienced veterinarian.

Tips, DIY & hacks
Feed earthworms, nightcrawlers, and gut-loaded insects every few days, dusting with calcium, and avoid overfeeding since captive tigers obese easily. Spot-clean burrows frequently, handle minimally with wet hands to protect their sensitive skin, and provide cork-bark or a buried hide; larval (aquatic) tigers need a filtered aquatic setup until they morph.
