2% UVB is required for froglets 2 months & older, no more than 3% UVB.

**UV rays help eliminate excess bacteria growth (not saying bacteria will not grow in the tank, but it will help lower it)

UVB is essential for frog’s growth.


Small froglets can be offered 1/8” crickets

As juveniles – 1/4” crickets -  Try house flies for an entertaining treat!

Adults can be upgraded to 1/2” – 5/8” crickets

**adults may be offered small roaches (if you want), they should equal the same size as the cricket.

***3 parts Herptivite to 1 part Calcium***


They are not exceptionally difficult to breed, but can be difficult to breed consistantly. Seasonal cycling, coupled with a large water volume and heavy feeding, can encourage breeding. Each female will lay between 300-1000 eggs, which quickly develop into voracious tadpoles that eat A LOT! After about 2 months in the water, the tadpole morph into dime to penny size froglets, which are initially gray in color.
