I overstocked my tank so I have to sell a few fish, I have a yellow tang that is a little too big for my tank and I have a blue hippo that I introduced to my tank with another blue hippo and they keep getting ich! No other fish has ever gotten ich in the tank and these guys get it 3 times already.I guess you can only have 1 per tank at least in a smaller tank. I'm going to treat them one more time and then separate them. 60 for the pair or 25 for the yellow and 35 for the hippo. You can have either hippo in the tank and the yellow tang for sale is the larger one. I would say at least 3 inches. Both fish eat anything you throw in the tank. Frozen or pellets, I'm convinced they will eat dog food or a hotdog if you threw it in there.
