I know they are not "monster fish" but i was talked into getting on yesterday for 2 or 3 bucks. hes pretty cute. about 6 inches. he is a blue grey mettalic color with many black spots and a light stripe on his side, very long whiskers. the spots make him look dalmation like. he has a wide head. and a frog like face. I am big on spotted animals. I was just wondering what do these guys eat usually? what do you all recomend? and they dont get bigger than 8 inches right?
