hypostomus cf. luteus

, 3"-5' , wild from the Uruguay river. Luteus come in 3 phases primarily this is a phase 1 which is a solid black fish. There is a chance that it can gain some gold in the fins and tail but may remain 100% black. We are labeling them as cf. because there is a chance it could be another member of this genus from the area which has other uncommon hypostomus that are black with spots.
