I raised some gray (or copes, not sure yet) from tad poles. they have been out of the water and tails are gone for 2-3d. None are eating yet (tried fruit flies and tiny blood worm pieces) they just aren't interested (the flies walk over their faces and they ignore the worms and flick them off their feet when they touch them). When should I get concerned? I know some froglets from some species may take days to a week before eating after the tail is absorbed, is this the case with these guys?
