Just picked this guy up today at my LFS. From what i've gathered they're fairly rare and I got a hell of a deal on him. I paid $80 for him and hes about 7-8". Very very cool looking cat. If anyone with experience keeping these guys wants to chime in feel free to. He has some scratches on his head but hopefully they will go away soon. So far so good, granted hes only been in the tank about 2 hours. I even caught him eating some tilapia already. Right now hes in a 75g with a 5" mala wolffish. Don't try to rip me on tank size because yes I do plan on upgrading him to a large tank once we move which will be in about a month or two. I've gotten mixed things about their max size, one site said around 4' and another one said most males reach about 2' with females getting a little larger.
