Goliath Frog (Conraua alleni)A.K.A. Slippery FrogDescription: Goliath Frogs are the largest frog species, growing over a foot in length and up to 8 lbs. They are brown to green in color. Unlike most frogs, the male grows larger than the female, but neither can call as they are mute. These frogs can live about 13-14 years if taken care of properly.Habitat and Tank Requirements: This species is native to West Africa. They do well with plenty of live plants and other things for them to climb, such as wood and rocks. Approximately 1/3 of their tank should be water. You can either use an under-gravel filtration system or clean the water every 2-3 days. You can use a small bowl just deep enough for the frogs to submerge themselves. If you decide to go with a filter, use common sense: a pump that is too small will leave the water dirty, while a too-powerful pump with filter out the microorganisms needed to maintain a healthy pH. Be sure there are no openings in the tank through which the frog can escape. A hole large enough for a frog to stick its head out of is large enough for it to escape. Because they are so large, Goliath Frogs obviously need a roomy tank. They can be kept in groups of 2 or 3 in a 40-60 gallon tank, however, as with all frogs, do not keep different species of frogs in the same tank. There is a risk of disease and parasites being spread between species, even if the carrier frog does not show any symptoms. These hardy frogs can survive in temperatures as low as 65º F and as high as 85º F. They prefer warmer temperatures during the day when they sleep and bask, and cooler temperatures at night when they hunt. LEDs or other low-wattage light bulbs work best for maintaining these temperatures.Diet: Goliath Frogs will eat just about anything they can fit in their mouth. You can feed them crickets, fruit flies, mealworms, wax worms, and any other insect small enough for them to ingest. They’ll also eat mice, fish, and other frogs. It is recommended that food be dusted with calcium to prevent bone softening.Handling: Allow your frog time to become accustomed to its new home before handling them extensively. Handling them little by little over a period of time lets the animal get used to you and reduces stress. They are not the easiest frogs to handle because of their size and agility. If they loose they can jump up to ten feet.
