Fire-bellied Toad

House a pair or trio in a semi-aquatic terrarium (paludarium) of at least 45 x 30 x 30 cm (roughly a 38 to 57 litre / 10 to 15 gallon footprint); 60 x 45 x 45 cm is better and comfortably holds a group of up to four. Split the floor space roughly 50/50 land and water. The land section can be firm cork bark, smooth river stones, or a bioactive soil mix topped with sphagnum moss and live plants (pothos, java moss, cryptocoryne). Fire-bellied toads are strongly aquatic and spend much of their time in the water, floating at the surface rather than diving; water can range from shallow up to about 10 to 15 cm (4 to 6 inches) as long as there are ALWAYS easy, reliable haul-out points (a gentle slope, stones, cork, or floating plants) so a toad can rest and climb out and never becomes trapped or exhausted. A tight-fitting mesh lid is essential; they are capable escape artists and climbers. Avoid loose gravel or bark small enough to be swallowed with prey, which risks impaction.

Insectivore. Staples are appropriately sized live crickets, dubia roaches, earthworms, black soldier fly larvae, and the occasional waxworm or hornworm as a treat. Feed adults every 2 to 3 days (juveniles daily); offer prey no wider than the space between the toad's eyes. Supplement sensibly rather than heavily: dust feeders with a plain calcium (no D3) powder at most feedings, use a calcium-plus-vitamin-D3 supplement only about 2 to 3 times per week, and add a broad amphibian multivitamin once weekly. If you provide a UVB source, use plain calcium (without D3) for dusting to avoid vitamin D3 overdose. Gut-load feeder insects for 24 to 48 hours before offering. AVOID: fireflies/lightning bugs (their lucibufagin toxins are rapidly fatal to amphibians), wild-caught insects (pesticide and parasite risk), any prey that is too large, and a diet dominated by fatty waxworms or mealworms (poor calcium ratio, promotes obesity and hypovitaminosis).

Keep this a COOL species. Ambient/daytime range 20 to 24 C (68 to 75 F); a night drop to 16 to 18 C is welcome. Never let the enclosure exceed roughly 28 C (82 F), which causes heat stress and death. No basking lamp or hot spot is needed; they are cold-tolerant and dislike heat. Humidity 50 to 80 percent, easily held by the water section, moss, and live plants. Use only dechlorinated or aged water (chlorine and chloramine burn amphibian skin); a slightly acidic to neutral pH around 6.5 to 7.5 is ideal. Change or lightly filter the water frequently, as they foul it quickly; a low-flow sponge filter helps but keep current gentle. UVB is not strictly mandatory if dietary D3 is provided, but a low-output 2.0 to 5.0 UVB bulb on a 10 to 12 hour cycle is beneficial and supports calcium metabolism; if you use UVB, switch feeder dusting to plain calcium without D3 to avoid overdose. Provide a regular day/night light cycle.

Gregarious and best kept in small same-species groups (a pair, trio, or up to four in adequate space); they tolerate and even seem to prefer company. Do not mix with other amphibian or fish species, as their skin toxins can poison tankmates in shared water. Sexing: breeding males develop dark nuptial pads on the first fingers and forearms and produce a soft repetitive barking call, especially after a cool-then-warm cycle; females are generally larger and more rounded. No pair bonding is required.

Enrichment centres on a varied, naturalistic environment rather than interaction. Provide live plants, floating cork, hiding caves, and gentle water they can float and paddle through. Live moving prey (scatter-feeding or letting them hunt crickets) is the single best behavioural stimulation. Rearranging decor occasionally and maintaining a genuine day/night and seasonal temperature rhythm keeps them active and can trigger natural breeding behaviour.
