Care notes
Outstanding algae grazer that controls hair algae and diatoms. May starve once algae is depleted; supplement with seaweed clips and algae wafers. Needs well-established tank.
Check the whole aquarium. Tank size alone does not establish compatibility. Confirm adult size, water overlap, social grouping, territory, diet, and the individual animals before stocking.
