Indonesian Horned frogs (Megophrys spp.)

Posted by Unknown on 11:59 PM with No comments
Imported from Indonesia as the Malayan Horned Frog, Megophrys nasuta, this species is in all probability the smaller species Megophrys montana. Our specimens have been collected on the island of Java. Despite having imported them several times, the largest specimen we have ever received has been around 7 cm, while the more frequently imported species known as the Malayan Horned Frog, Megophrys nasuta, grows much larger.

They are very beautiful and reasonably hardy frogs, and as the pictures show they can be quite variable in colors. This seem to change according to the individual specimens mood, and the way they are kept.

They feed greedily on anything that moves, and they love waxworms, which we use after their arrival due to the high fat content. Make sure you keep an eye on the frogs if you feed them crickets, removal of any uneaten cricket is a must, otherwise they do serious damage to the frogs` delicate skin.

As with the other members of the genus Megophrys the females are considerably larger than the males. The males are avid callers, with a sound quite pleasant to listen to in the late evenings.

The Indonesian Horned Frog usually hides within leaf litter during the daytime, so make sure you provide a layer of dead leaves for them, or plenty of other forms of hiding places such as pieces of cork bark. Keep their environment very clean, and do not expose them to temperatures too low. A heatmat can be used under a small part of their cage, but make sure the frogs can not get burnt from direct access to the heatmat, or otherwise overheat.

As in their natural environment, high humidity is required by frequent misting of their environment, equally good air circulation is important. They sometimes enter water and soak for a while, so it is advisable to give them access to a shallow waterbowl at all times.

Megophrys cf. montana is not commonly available in the trade, and as far as we know are not being bred in captivity. Cannibalism is know to occur within at least the larger Megophrys-species, we have always kept these frogs in larger mixed groups without any signs of cannibalism, despite some of the males being only half the size of the females.
