The short version

Fire-bellies are semi-aquatic, so they need both land and shallow water. Room temperature and 60–70% humidity work well. They eat crickets and small insects, and a calcium and carotenoid supplement keeps their bellies bright. The sections below walk through everything in detail.

01

Enclosure & set-up

Tank size & layout

An 18" x 18" x 12" terrarium or a standard 20-gallon long tank fits a small group. Use a sloped layout with large river rocks to separate a land area from a shallow water area.

Maintain 1–2 inches of dechlorinated water. Avoid small gravel or sand — both are an impaction risk if swallowed.

I personally love floating cork board. The frogs congregate on it.

Cover every gap (they escape)

Fire-bellies will climb the glass. Every hole needs to be covered or they will get out. I use screen-door repair tape to cover gaps — works great.

02

Water & lighting

Water quality is critical

Fire-bellies produce significant waste. Either perform regular water changes or run gentle filtration. A small heater helps if water temperatures drop too low — cooler water kills their appetite.

Pothos as a living filter

I like to use pothos vine in the water. Once it's established, it helps reduce nitrogen in the tank, and it gives the toads something else to climb on.

Lighting

Run a consistent 12-hour day / 12-hour night cycle. I like an overhead light with UVB — the pothos doesn't need it, but it grows better, and good plant growth is good for the enclosure.

03

Temperature & humidity

Temperature

Ideal range: mid-70s°F. My house was a steady 69°F before the baby came and the toads still bred late into the season. Mid-70s is great. Room temperature is ideal.

Temperatures in the high 80s can be fatal, especially with low humidity or low water. Don't use a full screen top — it dries them out. Classic aquarium hoods work well. A plexiglass piece cut to cover half the top with the rest as screen holds humidity nicely.

Use a digital thermometer. They're cheap on Amazon and worth it — certain windows reflect light in weird ways and create micro-climates in the tank.

Humidity

Keep humidity at 60–70%. Make sure there's proper ventilation — at least a half-screen top. Poor airflow plus high humidity leads to bacterial skin infections. Monitor with a digital hygrometer.

04

Feeding

What to feed

Fire-bellies are insectivores with strong appetites.

  • Juveniles: 1/8"–1/4" crickets
  • Adults: primarily 1/4" crickets

Additional feeders: fruit flies (melanogaster or hydei), small roaches, black soldier fly larvae, and waxworms (occasional treat only — they're fatty).

Supplements for color

I heavily recommend a calcium supplement. I also love Repashy Superpig — it's high in carotenoids, which intensifies the orange-red of Bombina orientalis bellies. Dust the food before feeding.
