Care Sheet: Allen's Goliath Frog (Conraua alleni)


Common Name: Allen's Goliath Frog, Allen's Slippery Frog.

Scientific Name: Conraua alleni.

Distribution: Western Africa.

Size: Sizes in excess of 6" can be expected, we have heard reports of individuals of 9”.

Sexing: The males of this species have 2 visible vocal sacs on the throat.

Requirements: These frogs are large individuals and therefore should be housed in a large terrarium, a 20-gallon (36”x12”x12”) tank would be adequate for 1-2 juveniles of 3” but will need to be moved to correspondingly larger tanks as they grow. They require a semi-aquatic set-up of approx. 60/40 water/land ratio.

The land area should be free draining with a substrate of sandy topsoil and moss. Pieces of cork bark, logs, rock and sturdy plants can be arranged to provide a number of hiding places.

The water area should be graduated from 2cm - 10cm with a base substrate of either gravel or sand, the water area can be lightly planted and rocks and logs should be placed to break the waters surface in a few places to provide areas to rest. The water will need to be filtered and partial water changed on a regular basis to avoid the build up of ammonia and bacteria in the water. We recommend you use the filter to produce a slight current on the surface of the water. Whilst doing the partial water changes it is a good idea to visually inspect the tank and remove, clean and replace any soiled items.

The tank will need to be heated to a daytime temperature of 25°C this can be done with a submersible water heater with built in thermostat. A light source should be provided by the means of a fluorescent UVB tube set on a 12hour light cycle.

Feeding: Juvenile frogs should be fed daily with a mixture of suitably sized insects including crickets, locusts and earthworms. The food items should be dusted with a calcium and vitamin supplement two-three times a week. Adult frogs should be fed every two-three days with a mixture of earthworms, adult locusts, crickets, cockroaches, super giant mealworm, beetles and it may be possible to train them onto suitably sized rodents. The food items should be dusted with a calcium and vitamin supplement once a week.
