not a bullhead. fins are differently shaped and it's got an overbite, which bullheads dont have.
I'm thinking along the lines of the genus Chrysichthys but I could be mistaken.
No problem, check the cat-elog on planetcatfish.com, look in the family claroteidae for genus chrysichthys, species in the genus can be tough to i.d. but im leaning toward chrysichthys nigrodigitatus.
I own a chrysichthys cf. nigrodigitatus, hes a great fish.
Thank's will have a look !!! Just wanted to know cuz my mate is changing his tank soon to smaller fish and im going to have this cat off him when he does !!!
