Relevant Information:

Description: The members of the Dolichancistrus genus are very similar to Chaetostoma but with a completely ossified edge to the snout. They also have stouter bristles behind the gill cover and longer pectoral fins and a growth of fine odontodes around the edges of the mouth. To differentiate this genus, Dolichancistrus have hypertrophied (elongate) odontodes on the side of the snout, small eyes and have 8 or more dorsal fin rays against 7 in the other ancistrins. Also, Dolichancistrus will develop a single hypertrophied odontodes in the evertible cheek mass (rarely 2 or 3) vs. many, and males will develop really long pectoral-fin spines. Aquarium Care: Conditions the same as Chaetostoma where they will need a good water flow in the aquarium with a sand substrate and plenty of hiding places. Diet: Great algae eater, but you will have to subsidise this food with algae wafers and vegetable foods such as cucumber, zucchini and lettuce. Will also except tablet and worm foods.
