L239

About

Formerly known in the trade as L239, Baryancistrus beggini is a compact loricariid catfish native to the rocky, fast-moving waters of Venezuela and Colombia, where it scrapes periphyton and associated microfauna from the surfaces and undersides of granite boulders along exposed sections of the Guyana Shield. Its appearance is quite distinctive within the pleco world: the body is uniformly dark brown to black, overlaid with a subtle turquoise to bluish sheen, and a noticeable keel runs along the lower flanks, formed by the angled shape of several midventral body plates above the pectoral fins. It stays small by pleco standards, which makes it workable in modest setups without the usual concerns about a suckermouth outgrowing the tank. Despite being labeled beginner-appropriate in terms of basic care, it is not a fish for a generic community setup. It can be territorial toward its own kind and toward other similar-looking plecos, particularly male-to-male, though its small size means a group can sometimes be managed in a larger tank with adequate rockwork and sight breaks. Keeping it alongside small, non-competing characids tends to work well. Breeding follows the typical loricariid cave-spawning pattern, with the male taking sole responsibility for guarding eggs after the female is driven away.
