Native to South American countries and the Amazon River basin, the Bristlenose Plecos are quite common in the aquarium trade for their unique appearance and algae-eating habits. This species of pleco inhabits slow-moving rivers with rocky substrates. 

Bristlenose are dark in appearance with small white or yellow spots covering their whole body. Justifying their name, the Bristlenose Plecos have long tentacle-like appendages or “bristles” on their head and face. Males have more prominent bristles. 

The bristles are used for courtship displays.

Zebra plecos are native to the Xingu River and Amazon River in Brazil. They inhabit rocky areas with fast-flowing water. This species of pleco, surprisingly, is carnivorous and feeds on small crustaceans and invertebrates. 

Apart from aesthetic reasons, there is no additional benefit associated with keeping Zebra Plecos. Many aquarists, deceived by their suckermouth, believe they’re algae-eaters, only to release them later in the wild and disrupt the native ecosystem. 

Zebra Plecos have a predominantly black body with bright white or cream-colored stripes running horizontally. Their fins also demonstrate such intricate patterns. This small species of plecos don’t go beyond a size of 3 to 4 inches.
