L144 Longfin Pleco (Ancistrus sp. L144 longfin)

The L144 Longfin Pleco, also called the Longfin Lemon Bristlenose Pleco, is a peaceful and attractive algae-eating catfish known for its bright yellow body and extended fins. It is a slightly larger and more elegant version of the L144 Shortfin Pleco, making it a showpiece in community and planted aquariums while still providing excellent algae control.

This hardy bottom-dweller enjoys aquariums with driftwood, hiding places, and stable water conditions. It actively grazes on algae, biofilm, and leftover foods, helping to maintain a clean tank. Its peaceful nature allows it to coexist with most community fish, including smaller species.
