Oriental Fire-bellied Toad

Overview

Fire-bellied toads are small, warty toads, brown-gray to bright green with dark spots on top. Their bellies are smooth and marbled red, orange or yellow ³. That color warns predators that their skin is toxic ³. They're active by day and social, and they're a popular first amphibian ¹².

Natural history

Oriental fire-bellied toads live in northeastern China, the Koreas and far-eastern Russia ³. They spend most of their time in slow streams and ponds within forests, meadows, river valleys and swampy scrub ³. In the wild they hibernate from autumn to late spring, often in small groups ³. Their tongues don't extend, so they lunge at prey and stuff it in with their front feet ²³.

When threatened they arch their backs and raise their limbs to flash their bright bellies, a pose called the "Unken reflex." If pressed further, they flip over and secrete a milky toxin ¹³.

Enclosure

• Semi-aquatic setup. Give them land that slopes into water. PetMD suggests about half land and half 1–2 inches of dechlorinated water ¹. Chicago Exotics suggests at least a third water, or a large shallow dish with 2–4 inches ². Keep it shallow. They're poor swimmers ².
• Size. A 10–15-gallon tank fits two or three toads. PetMD adds at least 4 gallons per extra toad ¹².
• Groups. They do well in small groups of similar size. Chicago Exotics suggests all females or one male with two females, since they bully smaller tankmates ¹². Separate toads that fight, and never mix species ¹.
• Furnishing. Add a screened, escape-proof lid, smooth rocks for climbing out of the water, and enough hides for each toad ¹².

Temperature & lighting

Above 82°F their skin dries out ¹. Put any heat pad on the land side, covering no more than a third of the floor, on a thermostat. Never use hot rocks ¹. Chicago Exotics advises against basking lights ².

Both sources recommend low-level UVB (2.0 or 5.0) for 10–12 hours a day ¹². PetMD says to replace bulbs every six months ¹. Turn white lights off at night ¹.

Humidity

Keep humidity at 50–80% (PetMD) or 50–70% (Chicago Exotics), and check it with a hygrometer ¹². Mist with dechlorinated water as needed ¹. Never use distilled water ²⁴.

Substrate

Build the land area from stacked flat rocks and moisture-holding coconut fiber, damp sphagnum or floating cork bark ¹. Paper towel or topsoil also work if cleaned diligently ². Avoid gravel and small bark pieces, which can be swallowed and block the gut, and avoid rough reptile carpet ¹. Fire-bellies dig, so pot live plants separately ².

Diet & supplementation

• Prey. Gut-loaded crickets, earthworms, silkworms, small roaches, mealworms and fly larvae ¹².
• Amount. Offer what they eat in 10–15 minutes ¹².
• Schedule. Juveniles every other day ¹². For adults, PetMD says once or twice a week, while Chicago Exotics says every 2–3 days ¹².
• Supplements. PetMD dusts with calcium plus vitamin D every feeding, and a multivitamin once or twice a week. Chicago Exotics suggests calcium weekly and a multivitamin every two weeks ¹². Unsupplemented insect diets cause metabolic bone disease ⁶.

Handling & temperament

Fire-bellied toads are docile and social, but they're for watching, not handling ¹². Their skin secretions aren't dangerous unless swallowed, but they can irritate. Keep them away from your eyes, mouth and any cuts ¹. Chicago Exotics notes that sensitive people may get a rash, and advises washing your hands right after contact ¹². When you must move a toad, use moistened powder-free gloves or a fine net ¹. Toads can carry Salmonella too ¹.

Health

Common issues

• Stuck shed, especially on the toes ¹.
• Red legs or belly (red-leg syndrome) and other bacterial or fungal infections ¹⁵.
• Eye problems. Discharge or a swollen eye ¹.
• Low immunity from wrong temperature or humidity ¹.
• Metabolic bone disease from unsupplemented diets ⁶.

Healthy toads shed regularly, often in one piece, and usually eat the skin ¹.

When to see a vet

See an amphibian vet for red discoloration, eye swelling or discharge, skin ulcers or growths, stuck shed that won't come off, weakness or appetite loss ¹⁵.

Breeding overview

In the wild, breeding starts when the toads emerge from hibernation in late spring ³. Males float and call with a soft "ting-ting." In the breeding season they grow rough nuptial pads and will grab almost anything that looks like a toad ³. Different females lay at different times, so breeding stretches out over a long season ³.

Legal & ethics

Chicago Exotics notes that many fire-bellied toads in the trade are wild caught, collected in Korea and China ². Ask for captive-bred animals where you can, and never release a pet.
