Diet & Nutrition
American Bullfrogs are carnivores. They will eat a variety of invertebrates including crickets, small waxworms, blood worms, earth worms, and roaches.
American Bullfrogs should be fed 2-3 times a week. Dust food with calcium powder every feeding, and a multivitamin once a week.
Housing & Habitat
American Bullfrogs are found in North America. American Bullfrogs can easily be housed together with similar size tank mates if kept in an adequately sized enclosure.
Enclosure Size
A single adult American Bullfrog must have a minimum cage size of 36"
Long x 18" Deep x 16" High. A larger habitat would be recommended for multiple specimens.
Substrate
American Bullfrogs are semi-aquatic. A terrarium with sand or large gravel for the water portion is acceptable. Peat moss, coconut fiber, or sphagnum moss is appropriate for a land portion. The terrarium may also be setup primarily terrestrial with a water dish large enough for the frog to submerge.
Temperature & Lighting
Temperature
American Bullfrogs require a basking temperature of 80ºF. The cool end of the enclosure can be as low as 70ºF.
Lighting
Lighting is not required for American Bullfrogs. For live planted terrariums or aesthetics, lights may be used. Low strength UVB can be used to promote plant growth and act as an anti-microbial. There is no current proof that this animal requires UVB light, although some keepers prefer to provide UVB.
Plant and Fish bulbs are not UVB bulbs.
Humidity & Watering
Humidity
American Bullfrogs require a humidity to be maintained around 60%. If the terrarium is set up semi-aquatic, the water portion should maintain humidity. In drier environments this can be maintained using a fogger, hand mister, or misting system.
Watering
With the terrarium set up semi-aquatic, the water portion will suffice for water if it is kept clean. Otherwise, a large water bowl with clean water should be provided. Always use de-chlorinated water or bottled spring water.
