Salamanders and Newts Care Sheet

Developed with and approved by a qualified veterinarian.

salamander newt care sheet

This care sheet covers a variety of species, including:

  • Tiger salamander – Ambystoma tigrinum
  • Fire-bellied newts – Cynops pyrrhogaster



Tiger salamanders are the world’s largest land-dwelling salamanders. They are found all over the U.S. and into Mexico and Canada where they burrow underground in marshes, woodlands and meadows typically near water. Tiger salamanders are not a single species but a group of closely related subspecies that vary in color and pattern. They are hardy, interactive amphibians that, when captive bred, are typically very tame and make great pets.

Fire-bellied newts are native to Japan and China where they live in or near water. They do not like strong water currents but instead are found in gently moving bodies of water. They are typically seen swimming slowly while exploring their habitats.

Typical appearance and behavior

  • Tiger salamanders come in several different colors and patterns, depending on subspecies, including light brown with black patches, black with yellow stripes and black with orange spots
  • Young salamanders typically have a spotted pattern that changes as they mature
  • Tiger salamanders are stout-looking with small eyes and muscular legs for digging—all adaptations for spending a lot of time underground
  • Salamanders may take time to adapt to a new habitat and may stay buried in substrate at first, eventually becoming tame as they learn that food is on the surface
  • Tiger salamanders make no sounds and will often move around their habitats, following their pet parents, when they are hungry and hopeful for food
  • Male tiger salamanders are thinner with flatter tails and a more prominent vent than females
  • Growing salamanders shed their skin (molt) every few days to every few weeks and usually eat the shed skin
  • Fire-bellied newts are named for the distinctive bright reddish-orange markings on their bellies, along with varying amounts of brown, black and white
  • Fire-bellied newts’ size varies, with females averaging 4-5" in length and males averaging 3-4"
  • During breeding, male newts develop a blueish, broader looking tail and a swollen cloaca
  • Newts breathe in oxygen and hold their breath when they dive



Care Difficulty Beginner
Average Life Span Up to 15-25 years with proper care, depending on species
Average Adult Size 11+ inches long for tiger salamanders, 3-5 inches long for newts
Diet Carnivore
Minimum Habitat Size 15-gallon tank for one adult



Habitat size

  • For a salamander, provide a 15-gallon glass, acrylic or plastic tank for a terrarium
  • For a newt, use a 15-gallon glass tank for a semi-aquatic terrarium
  • Two newts or two salamanders may be housed together in a tank 20 gallons or larger
  • Tanks should have a securely fitting screened lid to prevent escape and allow adequate ventilation, and they should be longer than they are tall to allow a larger area over which amphibians can explore
  • Salamanders and newts will reach adult size in under a year, depending on species and under ideal conditions.


Building your habitat


Salamanders can be housed in a terrarium

  • Substrate should be placed in the bottom with a shallow bowl filled with dechlorinated water in which they can soak
  • Salamanders prefer dampened sphagnum moss or a mulch-type substrate such as coconut husk fiber or cypress mulch
  • Substrate should be 3-4" deep to allow burrowing
  • Gravel and small pieces of bark are not recommended as substrate, as they are abrasive to amphibians’ delicate skin and are indigestible if eaten accidentally, potentially leading to life-threatening gastrointestinal obstruction
  • A moisture gradient should be provided with one end of the tank containing moist substrate, while the other end has drier substrate, so that pets can choose where they want to stay
  • Substrate should never be soggy


Newts prefer a semi-aquatic terrarium in which land and water are separated

  • Ways to set up a semi-aquatic terrarium include:
  • Burying a bowl of water in substrate
  • Providing a platform which newts can climb to escape water. Commercially available décor, cork bark or driftwood can be used as a platform
  • Large pieces of gravel substrate can be sloped in the tank bottom to allow exit to a dry area on one side of the tank
  • Water should be at least 1.5 times as deep as the length of the largest newt
  • Provide proper filtration to ensure optimal water quality to help maintain health. Ensure moderate, slow water circulation to mimic water currents and high oxygen levels found in the freshwater amphibian’s natural habitat. Water circulation should not be too rapid, as newts are poor swimmers in turbulent water
  • Stable water quality (pH, ammonia, nitrate, nitrite) and water temperature are critical to a newt’s health. If you are unsure of the tank’s water quality, bring a sample to Petco for free testing
  • Pieces of slate or large, smooth pieces of gravel, too big for newts to ingest, can be used as substrate in the water
  • Dry substrate in the tank can contain decorative artificial or live plants and similar substrate as a salamander tank
  • Avoid small gravel that can easily be ingested, leading to potentially life-threatening gastrointestinal tract obstruction
  • Reptile carpet also is not recommended, as it is too abrasive to delicate amphibian skin


Décor -

  • Salamanders like to burrow under cork bark or driftwood and hide under moss or plants but may dig under and uproot live plants
  • Newts like to explore and climb on live or artificial plants, driftwood or commercially available artificial stones. Real stones are not recommended, as they may fall on and crush delicate amphibians


Temperature –

  • Provide a tank temperature of 60-75°F
  • Monitor temperature with a thermometer
  • Most tiger salamanders’ and newts’ habitats will not need supplemental heat if the temperature does not fall below 60°F. Conversely, habitat temperature should not rise above 78°F, as higher temperatures can stress these amphibians and lead to health problems


Lighting –

  • Salamanders and newts require a 10-12 hour day light cycle using a low-wattage incandescent day bulb that does not emit a great deal of heat during daylight hours only.
  • Salamanders and newts benefit from low level ultraviolet (UV)B light from full spectrum bulbs for 10-12 hours a day to help ensure they make vitamin D in their skin to absorb dietary calcium
  • Higher levels of UVB light may cause eye and skin damage in amphibians
  • Be sure to provide hiding places so amphibians can hide from light as needed


Humidity -

  • Maintain habitat humidity at 70% by misting with dechlorinated water as needed every day
  • Substrate should be moist but not soggy; increase ventilation if it gets too wet
  • Provide a shallow bowl of dechlorinated water in which your pet can soak to stay hydrated and to increase habitat humidity
  • Monitor humidity with a humidity gauge


Cleaning your habitat

For semi-aquatic habitats:

  • If using a bowl of water buried in the substrate in a semi-aquatic terrarium, remove the bowl, scrub it with a reptile-safe habitat cleaner or 3% bleach solution, rinse it thoroughly, then replace the water (dechlorinated and at the appropriate temperature) daily before returning it to the habitat
  • If using a tank filled with water and décor or rocks as a dry land, change 10–25% of the total volume of water every 2–4 weeks, or as needed; change filter media monthly
  • Use dechlorinated water only


For terrestrial habitats:

Thoroughly clean the habitat at least once a week:

  • Place amphibian in a secure habitat
  • Scrub the tank and furnishings with an amphibian-safe habitat cleaner or 3% bleach solution
  • Rinse thoroughly with hot water so no residue remains; it is imperative that all traces of the habitat cleaner or bleach solution are gone
  • Dry the tank and furnishings completely and add clean substrate before putting amphibians back in the habitat


What Do Salamanders and Newts Eat

A well-balanced salamander or newt diet consists of:

  • A variety of insects including a base-diet of gut-loaded (recently fed) cricketsearthworms, beetles and roaches, plus superwormswaxworms, silkworms, hornworms, Phoenix worms and whiteworms
  • Worms may need to be chopped into pieces for small newts
  • Frozen, fresh or live bloodworms, brine shrimp and tubifex worms also can be offered in the water
  • Large salamanders also can be fed frozen/thawed pinkie or fuzzy mice occasionally as treats
  • Mealworms should be avoided, as their hard exoskeleton is difficult to digest
  • Salamanders and newts also can be fed some portion of their diets as commercially available dry food


Things to remember when feeding your salamander or newt:

  • Varying the diet is key to providing complete and balanced nutrition
  • Feed juvenile salamanders every 1-2 days and adult salamanders 2-3 times a week at night; feed juvenile newts daily and adult newts every other day
  • Sprinkle food with calcium supplement every other feeding and a multi-vitamin supplement once or twice a week
  • Tiger salamanders commonly become obese; limit feeding them high-fat foods such as waxworms
  • Be sure to remove uneaten food from aqua-terrestrial tanks if it is not eaten within 10-15 minutes; it will degrade the water quality and lead to health problems



Don't handle amphibians unless necessary. Always wear moist, powder-free gloves when handling, as amphibians can absorb bacteria and oils on your hands through their delicate, porous skin, which can harm them. Plus, all amphibians have small glands in their skin that secrete irritating toxins to scare off predators. Do not allow amphibians’ secretions to contact your eyes, mouth or open wounds. Use an appropriately sized, small-mesh, soft net to move or block the amphibian while doing habitat maintenance

For semi-aquatic habitats, water care is essential:

  • Maintaining great water quality with regular water changes and adequate filtration is important to help keep your amphibians healthy
  • Daily: Check filter, water temperature and other equipment
  • Weekly: Test water quality at least once a week

Avoid overcrowded conditions which are a major cause of stress and disease in amphibians
