Nice zoos and PBT there Greg! Make sure you stuff the bajesus out of your pBT with whatever it is he's eating now. I find that you can increase your success rate with them if you feed them heavily at the get go. They are extremely fickle fish and can go on hunger strikes for no apparent reason. If they haven't stored enough calories they can waste away quick. Then they get sick and continue to lose appetite and then all down hill from there sadly. Anyway, not meaning to scare you or anything. I know you said he is eating well so just take advantage of that and try to fatten him up.
