The Red Spotted Blenny or Orange Spotted Blenny is a beautiful algae eating reef fish. They are mostly peaceful, but does not tolerate other herbivorous blennies with the exception of a mate. They may sometimes bite or attack other herbivores like tangs in their territory, especially in a too-small aquarium. Some red spot blennies may nip at SPS corals or clams. Provide plenty of frozen or prepared herbivore blend foods and live or dried algae for the red spot blenny to feed on.
