Description

Excellent Algae Cleaner

Help keep the tank clean and reduce maintenance efforts.
Prevents Cyanobacteria & Hair Algae Growth

Actively graze on problematic algae like hair algae and film algae that can take over rocks and sand.
Stir Up the Substrate

They’re completely reef-friendly — safe for corals, fish, and most invertebrates.

Ideal for reef tanks or nano tanks as part of a “clean-up crew.”
