Relevant Information:

Description: Distinguished from all other species in the genus by the following combination of characters: anterior abdomen covered by plates, except for the area corresponding to the pectoral girdle, which usually lacks plates, when present in this region, plates are relatively small and few; posterior abdomen with a well-developed preanal plate, bordered anteriorly by a series of 3-5 usually polygonal plates; premaxillary and dentary teeth with unequal-sized cusps; uppermost caudal ray not prolonged in a filament; and snout tip with an oval naked area not reaching the last pore of the infraorbital sensory canal. Habitat: Inhabits small streams with swift current over rocky and sandy bottoms. Active mainly during the night and seeks shelter between rocks, gravel and crevices during the day. Reproduction: The Rineloricaria species are usually cave spawners, where the female will place their eggs after the male has cleaned inside. The male will then guard and fan the eggs until hatching. The eggs will hatch in 4-5 days whereas the male can now be removed. More breeding information can be found here in the articles breeding section. Aquarium Care: As with all Rineloricaria provide long leaved plants or bamboo stalks for them to hang on to. Diet: Omnivore. Vegetable food such as cucumber and other various foods such as tablet, flake and frozen.
