I have about 8 tadpoles from about 100 eggs laid by Mantella betsileo. They hatched about a month ago and I've been feeding them crushed Spirulina tablets and ReptoMin. They seem to be growing quickly. I am concerned about the metamorphosis. I have a tank set up with an inch or two of water and many Java moss "islands," but not sure about feeding. The adults are barely able to eat fruit flies. Given the froglets are much smaller, what are the reasonable options? It's cold out this time of year so I won't be able to collect too much from outside. Plus, when should I transition them from the dish to the vivarium?
