Relevant Information:

This Ancistrus species is typified by its unusually broad head flattened body and its black dody colour. The males head bristles are very thick and not branched at the end, unlike most of this genera. Both sexes have fleshy 'tentacles' but the males are bushier and longer. Inhabits clear running water, to a depth of 3 meters during dry season. Prefers narrow cracks of submerged rocks, small passages between superimposed rocks, or lives below flat rocks on the bottom. Aquarium Care: Provide caves and flat stonework where this species likes to hide under. Breeding: Not one of the easiest Ancistrus to breed although it has been achieved by accident. Diet: Likes a meaty diet which is somewhat different from most members of the Ancistrinae. Feed frozen foods such as bloodworm and pellet, tablet and pre-soaked flake
