A large and robust mantella, M. viridis can reach 30 mm (1.2 inches). They are mostly green, although some individuals appear yellowish. A black mask wraps around the face, and below it is a white stripe. In terms of pattern, some can appear similar to M. crocea, but are easily told apart from their larger size, more robust body structure, and white frenal stripe. There are reports of frogs that appear intermediate between M. viridis and M. ebenaui, and it’s been suggested that within certain populations the two may hybridize . The only known locality of M. viridis, Montagne des Français, is in extreme northern Madagascar, where they are reported to inhabit streambeds in dry, lowland forest.

Although M. viridis has a very restricted distribution, wild-caught frogs are still exported and are periodically available in the North American pet trade. They are also bred occasionally in captivity, with captive-bred frogs being available from time to time.

M. viridis are excellent captives because of their attractive appearance and large size. Being one of the biggest mantellas, they love to feed on larger food items such as crickets and wax worms, although they’ll also hunt down small Drosophila melanogaster for a snack. They are somewhat shy, although after heavy mistings and during warmer parts of the year, males are outgoing and will call in the open. A temperature range from 18°C to 26°C (64°F to 79°F) seems to work well, with the lowest temperatures occurring during a simulated dry season or at night, and those on the warmer side taking place during the days of a simulated rainy season.
