Ancistrus sp. "Rio Paraguay" L528

Meet the Ancistrus sp. "Rio Paraguay" L528, commonly referred to as the Redspot or Red Honeycomb Bristlenose. This compact catfish brings both reliable algae control and striking color to freshwater aquariums, making it a standout choice for enthusiasts who value both function and form.

Size and pattern: grows to about 10–12 cm (4–5 inches) in length. Its body features a rusty-red base with a distinctive dark honeycomb mosaic, delivering visual interest that’s easy to appreciate from across the tank.

Origin and temperament: hails from the Rio Paraguay basin, naturally hardy and peaceful in community settings. Its calm demeanor makes it a dependable tank mate for a wide range of peaceful fish, shrimp, and invertebrates.

Diet and job in the aquarium: a hardworking algae grazer that also takes biofilms and driftwood fibers from the tank surfaces. This behavior not only helps keep glass and rocks cleaner, but also supports overall tank hygiene by targeting biofilms that supplements alone might miss.

• Compact, gentle algae eater ideal for smaller or mid-sized tanks.
• Unique red honeycomb pattern adds color and personality without overpowering the aquascape.
• Easy to breed a welcome advantage for hobbyists looking to observe natural spawning and population growth.
• Bottom-dweller with driftwood affinity, naturally aligning with setups that include wood features and hiding places.
• Robust and adaptable, thriving across typical freshwater conditions with minimal specialized care.

Ideal setups and practical tips: place in a peaceful community tank with compatible fish, soft lighting, and ample driftwood or caves to satisfy its natural behaviors. Provide gentle water movement and regular maintenance to keep biofilms steady, which this fish will actively graze on. Its preference for driftwood makes it an outstanding companion for tanks that emphasize natural décor and habitat complexity.

Why choose the Rio Paraguay L528? Its combination of a distinctive rusty-red, honeycomb pattern, reliable breeding, and steady algae-clearing activity sets it apart from other bristlenose catfish.
