We can't feed them pellets. This is part of a research project studying live feed vs pellets. (And the kids would disagree that pellets are a better food.
) The little ones are getting daphnia, mosquito larvae and some of the blackworms, all things they would eat in the wild, so they aren't starving. We're just worried about the aggressive behavior overall.The pellet tank is the control tank and it's down to only one fish as it is, one of the biggest that was in there. Is it possible he bullied the others? We didn't see any cause of death, water parameters were great, we added salt, we just assumed it was overall stress of being moved or something bacterial/viral we couldn't see.
Maybe these tanks are just too small to keep bluegill, even at such small sizes? They do appear to be a bit aggressive as a species.
