Bristlenose Pleco

The Bristlenose Pleco is a compact freshwater catfish with earthy markings and a busy grazing habit. It explores wood, glass, and rock surfaces throughout the aquarium, often becoming more active as the lighting softens. Mature males usually develop the characteristic bristles that give this fish its name.

Aquarium setup

A well-maintained aquarium of around 30 gallons or more provides a useful starting point for one adult. Expect an adult size of roughly 10–15 cm, depending on the strain. Keep stable tropical water around 23–27°C (73–81°F), with smooth substrate, shaded caves, and driftwood. Regular maintenance is still essential even with an algae-grazing fish.

Diet and feeding

Feed vegetable-rich sinking foods and wafers, supplemented with blanched vegetables and occasional protein foods. Provide its own measured meals instead of relying on leftovers from other fish. Remove uneaten food to protect water quality.

Compatibility

Generally suitable for peaceful community tanks. Males can compete over caves, so provide extra floor space and separate shelters when keeping more than one. Make sure other bottom feeders do not monopolize the food.
