Habitat: Ancistrus brevipinnis occurs in several habitats in the Patos lagoon system (RS), being more common in mountain streams. It usually moves over the rocky bed or through the interstices formed by gravel and stones distributed over the bed in stretches of current, being more active at night. It has a detritivorous eating habit. The maximum adult length varies between 14.0 cm for males and 12.6 cm for females (Rosa et al . 2008). Sexual Differences: Males as per this genus have bushy tentacles on the head, whereas the females have them shorter. Reproduction: The female lays her eggs in caves or crevices... that the male has chosen and cleaned.... as a cluster. The male usually then guards the eggs after ejecting the female. 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. Some species have different requirements in the aquarium so best to read up on the species you have whereas if they need higher oxygen requirements or not, or if they prefer cooler waters if they originate from the southern parts of South America against the species from further up north. Diet: Vegetable foods such as cucumber and courgette and also tablet and meaty foods.
