Yeah I was told when young got tore up by his tankmates??? I picked him up free about 7" or so had to save him from his 30 gallon home of 2 1/2 years got em in my 55 quarintine tank thats just bare tank so a bit more room for him. Not sure if he's stunted wish I could put him back in my 220 but instantly tore up my firemouth who thought he was tough and would probably tear up everyone else in there..... So taken my time to look for a better home, awesome personality its like he has a horn on him lol.
