I have 8 firemouth juviniles that I'm growing out. My plan is to keep one maybe two pairs of them. My question is if I have two pairs and one pair has fry will the other pair attempt to eat them? My next question sounds a little weird, kind of sinister really but, if I pull the fry out and wait one week and put some back into the tank will the fish eat them?
