my butta is around 15-16inches now and i have a smaller 9-10inch one too mine will only take so much beating from my 11inch red devil before he starts to fight then when the fights are done the tank is calm for like 4 months and then the cycle starts over but if i didnt have that red devil in there the butta would probably kill everything they keep each other in check i only have pictures of him when he was 14.5 ill post just the big butta tho
