Sorry, i can't advise you on that one. I did not fare well with my retf's. I mainly keep white's currently. I do believe, however, that there is a thread in the tree frog subforum about feeding retf's. If not, start a new one, but search first. Lynn and Heather are definitely 2 ladies to talk to about retf's. The one piece of advice i will give you on them, buy only captive bred frogs from a good breeder. Michael novy of rainforest junkies comes highly recommended and when.i get retf's again, i will most certainly get them from him.
