The fish, up close
Bristlenose catfish, scientifically known as Ancistrus, are small and peaceful freshwater fish characterized by their bristle-like tentacles on their snouts, which are more prominent in males. These catfish have a flat, wide body with a mottled pattern that helps them blend into their natural environments. They are excellent algae eaters, making them popular choices for controlling algae growth in aquariums. Bristlenose catfish are hardy and adaptable, making them suitable for beginners and experienced aquarists alike.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
These catfish are peaceful and non-aggressive towards other tank mates. They are nocturnal by nature, so they are most active during the night. Bristlenose catfish are bottom-dwellers and spend much of their time grazing on algae-covered surfaces or hiding in caves and crevices.
Tank planning
Maintaining good water quality is essential for the health of Bristlenose catfish. They prefer well-oxygenated water with moderate flow and a temperature range of 22-26°C. Provide plenty of hiding spots in the aquarium, such as caves, driftwood, and plants. Regular water changes and a varied diet will help keep these catfish healthy and thriving.
