The Chocolate Pleco (Pterygoplichthys scrophus), also known as the Rhino or Alligator pleco, are a large species of pleco catfish. This listing is for sub-adult Chocolate plecos of a light brown colouration.
THESE ANIMALS ARE VERY LARGE AND CANNOT BE KEPT IN SMALL AQUARIUMS.
These fish are omnivores that will adapt to any diet, but are commonly bought to help control algae growth on glass. While these animals will eat algae, they are also extremely messy; their large bioload may cause accelerated algae growth. These fish are very hardy and do well in temperatures from the low 70's to low 80's. Because these fish grow up to 10+ inches in length and have a high bioload, they require at least 100 gallons per Chocolate pleco.
These fish can be kept with almost any other fish species. They do well in large community tanks. They can act aggressively towards other large bottom feeders if there is not enough room. These fish will uproot and eat most aquatic plants. Sometimes these fish will attempt to eat other small fish, or attempt to latch on to other larger fish. These behaviors can be avoided by making sure the pleco is well fed and has access to natural driftwood at all times.
