i know. some of them looks like pacman frogs that i have seen! they seem like sloths of the frog world but i guess they do alright since they are actually destroying the native frog species...... but back to the original question asked..... i can't give you much insight into diet for your frog, however i would assume as with any captive kept amphibians, it is a good idea to give variety to them. in the wild, they have variety in their diet (crickets, worms, different insects) so one would assume it would make them healthier if you switch it up a bit
