Pet Newts: Fire-Bellied Newt Care and the Law

Fire-bellied newts are small (about 3–5 inches, 8–13 cm), mostly aquatic amphibians that can live 15–25 years. They need cool, clean, dechlorinated water (about 60–75°F, 16–24°C, never above 78°F, 26°C), a gentle filter, a land area to climb onto, and a varied diet of worms and insects. Their skin secretes toxins, so don't handle them bare-handed. Never take newts from the wild.

Cool water, slow currents and somewhere to climb out.

What Pet Newts Need

The newts sold as pets are mostly Asian fire-bellied newts, named for their bright orange or red bellies, plus a few related species. They spend most of their time in water but need somewhere to climb out. They are calm and interesting to watch, and they can live for decades.

Tank and Water

PetMD suggests at least a 15-gallon (57-liter) tank for one newt and 20 gallons (75 liters) for two, longer than it is tall, with a screened lid; newts are good escape artists.

Water at least 1.5 times as deep as your longest newt, dechlorinated with a water conditioner.
A gentle filter: newts swim poorly in strong currents.
A land area they can reach easily: a sloping bank, cork, or a floating platform.
Floor: bare, sand, or stones too large to swallow.
Water changes: test the water and change 10–25% every two to four weeks.

Keep It Cool

Fire-bellied newts need cool water: about 60–75°F (16–24°C), and never above 78°F (26°C). A heater is rarely needed in a home; summer heat is the bigger risk, so keep the tank out of direct sun and away from heaters. These are typical ranges from a veterinary-reviewed care sheet; check with your vet or a specialist keeper.

A Cool, Clean Newt Tank

A long 20-gallon (75-liter) tank with a secure lid suits two newts. A sponge filter keeps the flow gentle, and a water conditioner and test kit keep the water safe. A floating platform or cork gives a land area, a thermometer warns of summer heat, and powder-free gloves are for the rare times you must handle them.

Diet

Feed a base of gut-loaded worms and insects (earthworms, crickets, roaches), plus bloodworms, brine shrimp or a sinking newt food for variety. PetMD suggests juveniles daily and adults every other day, removing leftovers within 10–15 minutes.

Don't Handle With Bare Hands

Newt skin glands produce toxins. Handle only when necessary, with powder-free gloves moistened in dechlorinated water, and keep secretions away from your eyes, mouth and cuts. Wash your hands after any tank maintenance. Never house different amphibian species together.

Wild Newts Aren't Pets

Don't collect newts from ponds or the wild. In the UK, great crested newts are strictly protected: it's illegal to capture, disturb, possess or sell them, with heavy penalties. Native amphibians elsewhere are often protected too. If you want newts in your life without keeping them, a wildlife pond is the way.

The Law: Rules Differ by Country

Rules on newts and salamanders differ by country, partly because of a fungus (Bsal) that is deadly to many salamanders.

United States: many salamander and newt species, including the fire-bellied newts (genus Cynops), are listed as injurious wildlife. Importing them is banned, and moving them across state lines is restricted. Check with the US Fish and Wildlife Service and your state.
United Kingdom: great crested newts are strictly protected (gov.uk). Ask APHA about the rules on importing pet amphibians.
European Union and elsewhere: trade in salamanders and newts has health rules in many countries. Check with your national authority.

Rules change, so check with your national authority before you buy.

Frequently Asked Questions

Handling and temperature come up most.

Can I hold my newt?

It's best not to. Their skin produces toxins and is delicate. If you must, use powder-free gloves moistened with dechlorinated water, and wash your hands afterward.

Do newts need a heater?

Usually not. Fire-bellied newts need cool water, about 60–75°F (16–24°C), and overheating is the bigger risk.

How big a tank do newts need?

PetMD suggests at least 15 gallons (57 liters) for one and 20 gallons (75 liters) for two, with a land area and a secure lid.

Can I keep newts from my garden pond?

No. Wild newts should stay wild, and some, like great crested newts in the UK, are strictly protected by law.

Are fire-bellied newts legal in the US?

Fire-bellied newts are listed as injurious wildlife in the US, so they can't be imported and interstate moves are restricted. Check with the US Fish and Wildlife Service and your state.

How long do newts live?

Often 15–25 years, depending on the species.
