Eastern Tiger Salamander

Overview

The tiger salamander is the largest land-dwelling salamander in North America ¹³. Adults are stout, usually 17 to 33 cm (about 7–13 in) long, with yellow, tan or olive blotches on a black background. No two have the same pattern ³. PetMD lists 15 to 25 years as a possible lifespan with proper care, depending on the species ¹.

Captive-bred tiger salamanders are robust and settle in well. New arrivals often bury themselves at first, then become bolder once they learn food appears at the surface ¹.

Natural history

ADW describes tiger salamanders as ranging widely across North America ³. PetMD notes that "tiger salamander" covers a group of closely related forms with different patterns and colors, so ask exactly which one you're buying ¹. Adults live on land in forests, grasslands or marshes and spend much of their time underground. Burrowable soil is a key habitat need ³. They migrate to ponds to breed in late winter or early spring, and the aquatic larvae transform into land-dwelling adults ³. Some individuals stay in the gilled larval form for life ³.

Enclosure

• Tank size. PetMD recommends at least a 15-gallon tank for one adult, or 20 gallons for two. Choose one that's longer than tall, with good ventilation and a secure screen lid ¹. Chicago Exotics notes a large plastic storage box works as well as an aquarium ².
• Hides. Give them plenty of hides such as cork, driftwood or moss, because they love to burrow ¹².
• Water dish. Keep a large, shallow dish of dechlorinated water they can soak in. Change it daily, or whenever it's soiled ¹².
• Tankmates. Tiger salamanders can share a large enclosure if no one is aggressive. Separate fighters, and never mix different amphibian species ¹.

Temperature & lighting

Tiger salamanders do best cool, between 60°F and 75°F ¹. Long periods above 78°F (25.6°C) are dangerous, and both sources warn against letting the tank get that warm ¹². Most need no added heat, and you should keep the tank out of direct sun ¹.

PetMD recommends a 10–12 hour day/night light cycle and a low-output (2.0 or 5.0) UVB bulb, replaced every six months. Higher UVB levels can harm amphibian eyes and skin ¹. Always provide shade to retreat to ¹.

Humidity

PetMD suggests keeping humidity around 70% by misting the substrate daily with dechlorinated water. The substrate should be moist but never soggy ¹. Both sources recommend a moisture gradient, with one side damper than the other, so the salamander can choose ¹².

Substrate

Use 3–4 inches of a moisture-holding, burrowable substrate such as coconut fiber, topsoil, a forest-floor mix or damp sphagnum ¹². Moist, unbleached paper towels work well for quarantine ². Chicago Exotics warns that acidic substrates such as peat moss can cause fatal salt loss through the skin ².

Never use gravel or small bark pieces that could be swallowed during feeding, since swallowed pieces can be fatal ¹². Avoid rough reptile carpet ¹.

Diet & supplementation

• Staples. Earthworms, crickets and other gut-loaded insects ¹².
• Treats. Waxworms, hornworms and an occasional frozen-thawed pinky mouse. These are high in fat and shouldn't be staples ¹².
• Mealworms. PetMD advises against them. Chicago Exotics lists freshly shed ones as acceptable ¹².
• Live rodents. Never feed them, and never microwave frozen ones ¹.

How often: PetMD suggests feeding adults 2–3 times a week at night and juveniles every 1–2 days ¹. Chicago Exotics ties feeding to temperature: about once a week at 65°F or cooler, and at least twice a week when warmer ². Remove uneaten crickets within 24 hours, since they can bite ². Tiger salamanders become obese easily ¹.

Supplements: Dust insects with calcium plus vitamin D and an amphibian multivitamin ¹. Merck notes that pet amphibians can develop metabolic bone disease when their diet lacks the right balance of calcium, phosphorus and vitamin D3, or when they get too little UVB ⁶.

Handling & temperament

Tiger salamanders are calm and docile but don't enjoy handling, so keep it to a minimum ¹. When you do need to move one, wear powder-free gloves moistened with dechlorinated water. Human skin carries oils and bacteria their porous skin can absorb ¹. Keep their skin secretions away from your eyes, mouth and cuts, and wash your hands afterward ¹.

Like other amphibians, they can carry Salmonella ⁸.

Health

Common issues

• Obesity, from rich foods ¹².
• Gravel or substrate impaction ¹².
• Overheating stress ¹².
• Dehydration, if the enclosure dries out. A water bowl is a safety net ².
• Metabolic bone disease ¹⁶.
• Bacterial and fungal skin infections ⁷.

When to see a vet

PetMD recommends a yearly checkup. Go sooner for swollen, sunken or crusted eyes; pink ulcers or sores on the skin, especially the nose; stuck shed, particularly around swollen toes; or trouble walking or holding a normal posture ¹.

Breeding overview

Compared with females, males are slimmer, with flatter tails and a more prominent vent ¹. In the wild, adults return to ponds after warm late-winter or early-spring rains and court at night ³.

Legal & ethics

• U.S. federal law. In January 2025 the U.S. Fish and Wildlife Service added the whole genus Ambystoma to its injurious wildlife list to keep out salamander chytrid fungus (Bsal) ⁴⁵. Importing them, or shipping them between the continental U.S., Hawaii, Puerto Rico, D.C. and U.S. territories, requires a permit. Moving them between states within the continental U.S. isn't federally prohibited ⁴.
• If you already own one. Pet owners don't need to do anything if the animal has never been covered by a permit ⁴.
• Native wildlife rules. Because they're native, many states regulate collecting or keeping them, so buy captive-bred and check your state's wildlife rules.
• Never release. Never release a captive salamander ⁴.
