Maintain these water conditions for optimal health and vibrant colors
Carrying a striking red-and-black colour form, this bristlenose catfish (Ancistrus sp.) brings extra visual punch to the bottom of the tank while doing the unglamorous job of grazing algae. The contrast of warm reddish tones against darker markings makes it a favourite among keepers who want a working catfish that also looks the part.
It is a genuinely easy fish: peaceful, adaptable and long-lived, with a potential lifespan of around ten years. Adults sit in the 10–15 cm range. Although classed as an omnivore, it grazes algae as its main occupation, so vegetable-led foods, sinking wafers and a chunk of driftwood keep it healthy and busy.
A 60-litre tank or larger, dressed with wood and caves, suits it well. It accepts moderately soft to moderately hard water across the listed band, which keeps maintenance straightforward. A hardness range of 2 to 15 dGH covers most home aquariums, and a temperature anywhere between 23 and 28°C will keep it comfortable and grazing.
One thing worth planning for is final size: this colour form can reach 10 to 15 cm, so it earns its keep but needs the floor space to match. Given a decade-long potential lifespan, it is best thought of as a permanent member of the tank rather than a quick fix for an algae problem.
This red-and-black bristlenose mixes happily with peaceful community fish including tetras, rasboras, corydoras, livebearers and dwarf cichlids. Keep it away from large aggressive cichlids, very territorial bottom catfish, fin-nipping species, predators big enough to take juveniles, and other bristlenose plecos in an undersized tank. Being a peaceful, easy-care species it suits keepers of all experience levels, asking only for clean water, a vegetable-led diet and wood to graze on. With a potential lifespan of around ten years and an adult size in the 10 to 15 cm range, it is a fish to plan a tank around rather than an afterthought.
