The fry then cling to the sides of the cave and when they use up their yolk sac, which is around the four to seven day period, they will be ready to feed on infusuria, vegetable matter, brine shrimp naupli or micro worms. In a community tank a few will survive if enough hiding places are afforded to them. Aquarium Care: The Ancistrus genera make good community fish where they do not grow too big for the aquarium.

IUCN Red List

The rapid expansion of agricultural and urban borders, with the consequent degradation of the water quality of the various aquatic spaces, constitutes a serious threat to this species, restricting it to five locations and causing an inferred continuing decline in habitat quality and EOO. Together with a small range therefore (EOO equating 5,859 km2), this species is assessed as Vulnerable (IUCN 2023).
