A resident of fast-moving, rocky streams in Southeast Asia, Black Lizard Loaches use their modified pectoral fins to attach themselves to the rocky substrate and move among the rocks in search of food. In the wild, they are grazers and generalists, feeding on algae, biofilm, and small insects and crustaceans. In the aquarium, they do best when kept under similar conditions to their wild habitat rocks, ample current, and well-oxygenated water. Although they will accept a number of prepared sinking foods, its important to supplement their diet with algae- or veggie-based food.
