Overview
The mega clown pleco (L340) is a dwarf pleco for a small community tank. It is a good pick for a keeper past the beginner stage.
Did you know
The mega clown pleco is willing to come out in daylight, which is unusual for a Hypancistrus. That habit is a big part of why it stays popular despite its confusing pile of trade names.
Caring for the mega clown pleco (L340)
A mega clown pleco (L340) suits a tank as small as 20 gal (75 L). Give it caves and hiding spots. Keep the water warm, flowing and well oxygenated, at 79 to 86°F (26 to 30°C) and a pH of 6.0 to 7.5.
It is a carnivore, like other Hypancistrus, and does not graze algae. Feed protein-rich foods such as sinking carnivore pellets, frozen bloodworms, brine shrimp and gel diets. Do not rely on algae wafers as a mainstay.
The mega clown pleco is mostly peaceful in a community. It is fine alone but often does well in a small group. It has a comparatively bold, outgoing personality for a pleco. Breeding it is of moderate difficulty.

In the wild
The mega clown pleco comes from warm, rocky, fast-moving tributaries of the Orinoco basin in Colombia, including the Rio Tomo. It shelters in crevices and hunts through the substrate for insect larvae and small invertebrates.
