Description
Antsouhy Tomato Frog
Scientific Name: Dyscophus insularis
Common Name: Antsouhy Tomato Frog
Species Overview
Size: Adults typically reach 2.5–3.5 inches (6–9 cm), with females slightly larger than males.
Appearance: Antsouhy Tomato Frogs are bright red to orange in coloration, with smooth, slightly waxy skin. Their body is rounded and compact, with a broad head and short limbs. Some individuals may have subtle spotting or darker patches.
Distribution: Endemic to Nosy Antsohihy and surrounding areas of Madagascar.
Habitat: Terrestrial, inhabiting moist forest floors, leaf litter, and swampy areas. They prefer shaded, humid environments and spend much of their time partially buried or concealed under vegetation.
Behaviour: Slow-moving ambush predators feeding primarily on insects. When threatened, they secrete a sticky, white toxin that can irritate skin and mucous membranes.
Captive Care
Enclosure: A single adult should be housed in a 12 × 12 × 12 inches (30 × 30 × 30 cm) enclosure with a deep substrate (3–4 inches / 8–10 cm) of soil or coco fibre for burrowing. Larger adults may benefit from an 18 × 18 × 12 inches (45 × 45 × 30 cm) enclosure for additional floor space. Include leaf litter, moss, and low hides for security.
Temperature and Humidity:
Warm area: 75–80°F (24–27°C)
Cool area: 70–74°F (21–23°C)
Humidity: 75–90%, maintained with frequent misting and a damp substrate.
Lighting: Low-intensity lighting with a 12-hour light cycle is sufficient. Low-level UVB may be beneficial but is not essential.
Diet: Feed small insects such as pinhead crickets, fruit flies, and springtails. Prey should be appropriately sized and gut-loaded when possible.
Behaviour in Captivity: Sedentary and slow-moving. Secretes a defensive toxin when stressed; handling should be minimal.
Special Considerations:
• Maintain high humidity and a damp substrate
• Provide dense cover and burrowing opportunities
• Avoid handling due to toxin secretion and stress
Taxonomy Note
Antsouhy Tomato Frogs belong to the genus Dyscophus, part of the family Microhylidae, a group of small, terrestrial frogs native to Madagascar. Members of this family are characterized by their rounded bodies, short limbs, and specialized burrowing and ambush behaviors. Dyscophus insularis is one of the more vividly colored species, highly regarded for its bright red-orange coloration and defensive secretions.
Genetics Note
Naturally occurring species with no recognized captive-bred morphs.
