This dark beauty will help to rid your aquarium of unsightly hair and string algae. Although it rarely bothers Soft Corals or LPS (Large-polyped Stony) Corals it has been known to nip at SPS (Small-polyped Stony) Corals. Otherwise the Black Sailfin Blenny is completely reef safe, and beneficial to the reef aquarium.
Provide plenty of live rock with microalgae for it to graze on.
Feed herbivore preparations containing marine algae and spirulina algae. They will eat Nori (dried seaweed) and live macro-algae.
