my 3" bgk is in a growout tank that is under my main tank so it is hard to see in there because it is only a couple inches off the floor after the 2nd day I have only seen him once and that was last water change when I picked up his hide to verify he was still alive. I have 2 bichirs in there that are 3" and 4" so I put shredded tilapia in there daily I was also putting bloodworms but it just got too expensive putting them in both the growout and the main tank(it's all my fire eel will eat) I also have a large breeding population of guppies in the tank so he has access to healthy feeder fish at all times I really can't wait till he is big enough for the main tank
