Maintenance Alert

For tadpoles: Prepare an aquarium with a minimum of one-half quart of dechlorinated, or aged, water per tadpole. Successful rearing of tadpoles relies on maintaining clean water. Change half the water at least twice a week. Tadpoles eat algae or may be fed boiled lettuce. For adults: Create an aquatic habitat with a water depth of 1 to 2 feet. Change 1/3 of water daily with dechlorinated, or aged, water. Feeds on small fish or crayfish. Lifespan is 8 to 12 years.

Product Details

“Jug-o-rum, jug-o-rum!” The American Bullfrog is easily recognized by its tell-tale call. Dubbed the “bullfrog” because of the similarity to the sound of a mooing cow, this amphibian is an amazing creature to observe in a classroom setting. Bullfrogs have an olive green back and sides blotched with brown markings along with a whitish belly spotted with yellow or grey. These frogs are completely aquatic, which allows for students to create fun underwater habitats! Students become herpetologists as they witness bullfrogs go from tadpoles to full-grown adults! Live tadpoles will develop into adult frogs with 4–6 body length. Metamorphosis of bullfrog tadpoles to young frogs is slow and can take 4–12 months for complete resorption of the tail.
