With their nimble fingers, Amano shrimp are perfect for reaching narrow gaps and consuming various types of algae, including black beard algae. Keep them in groups to maximize algae control.

Amano Shrimp

Ornamental snails from the Neritidae family, like olive nerite snails, are efficient scavengers and algae eaters, particularly for tough green spot algae. Their eggs won't hatch in freshwater, preventing overpopulation.

Nerite Snails

While not as efficient as Amano shrimp individually, cherry shrimp breed easily and help prevent algae buildup when kept in colonies. Their vibrant colors add beauty to aquariums.

Cherry Shrimp

These dwarf suckermouth catfish are ideal for eating diatom algae and can fit into tight spaces. Provide plenty of food like Repashy Soilent Green for their small size.

Otocinclus Catfish

SAEs are effective cleaners for hair algae and leftovers in larger aquariums. Keep them in groups to mitigate territorial behavior.

Siamese Algae Eater (SAE)

Known for their voracious appetite for hair and black beard algae, these fish are suitable for unheated tanks with fast-swimming tank mates.

Florida Flagfish

Peaceful and smaller than other plecos, bristlenose plecos are adept at devouring algae and keeping driftwood clean. Feed them a varied diet to ensure optimal health.

Bristlenose Plecostomus

Mollies constantly pick at algae on various surfaces and readily reproduce in suitable conditions. Monitor their health if transitioning from brackish water to freshwater.

Molly Fish

With a taste for fuzzy algae, rosy barbs are relatively peaceful and come in various color variations. Keep them in groups in sizable tanks to reduce aggression.
