Temperament: Peaceful, except with other blennies of the same shape
Diet: Herbivore
Care:
Shy fish that requires rockwork to hide in and graze on. This fish feeds mainly off of film algae on rocks and glass, so a mature system of 30 gallons or more is best. Feeding can be supplemented with seaweed sheets and/or veggies, though I’ve never had one accept these foods. The algae blenny is a peaceful community fish but may get territorial/aggressive with other blennies of the same shape. Only one per tank should be kept unless it’s a large system or if it’s a mated pair. This blenny may nip at SPS corals and clam mantles as well.
ph: 8.1-8.4
Temperature: 72-78 degrees fahrenheit
Potential Size: 4-5″
Water Region: Within rockwork at all levels
Activity: Diurnal
Color: Mottled, brown, tan, gray, white
Mouth: Wide
Acclimation: Slow acclimation over a 1-2 hour period. Float to match temperature and add water every 15-20 minutes.
Breeding: Couldn’t find any breeding info on this fish so it’s assumed it’s not being bred in captivity yet.
Comments: Provided there is plenty of film algae in your tank, this fish is a great addition to any reef or fish-only tank. They are full of personality. Care should be taken to keep the tank top secure as these fish will jump out.
