I just got this guy and I made a newbie mistake. I didn't research it before I bought him. I put him in my tank and he started trying to eat the smaller fish. So my kids were unhappy. I caught him and he's in my sump. I don't really want to sell him so if anyone has a different fish that you want to trade for him. LMK want you have. Otherwise he'll be my excuse to put up another tank. lol.
