About the Bristlenose Catfish
Ancistrus variolus is a type of bristlenose catfish. These fish get their name from the small, branched tentacles or "bristles" that grow on their snouts, especially on the males. These bristles are thought to help them sense their surroundings or attract mates.
What It Looks Like
Like other bristlenose catfish, Ancistrus variolus has a flattened body and a wide head. Their mouths are shaped like suckers, which they use to cling to rocks and wood in fast-moving water. This special mouth also helps them scrape off algae and other food. Their bodies are covered in bony plates, which act like armor to protect them from predators.
Where It Lives
This little catfish lives in the Ampiyacu River basin in Peru, which is part of the vast Amazon River system in South America. They prefer freshwater environments like rivers and streams. These fish are often found on the bottom, hiding among rocks, driftwood, or plants. The water in their natural habitat is usually warm and well-oxygenated.
What It Eats
Ancistrus variolus is mainly a herbivore, meaning it eats plants. Its sucker mouth is perfect for scraping algae and other plant matter from surfaces like rocks and submerged wood. They also eat detritus, which is decaying organic material found on the riverbed. This makes them important cleaners in their ecosystem.
Life and Behavior
These catfish are mostly active at night, which means they are nocturnal. During the day, they often hide. They are generally peaceful fish, but males can sometimes be territorial, especially when they are protecting their eggs. Like many other catfish, they lay their eggs in caves or hollows, and the male often guards the eggs until they hatch.
