Oyster Blenny

Omobranchus Blennies should be added to well established aquariums with plenty of swim room. Rock work should be provided for perching, hiding and grazing. Omobranchus Blennies are considered to be easy but may become aggressive and territorial towards fish of similar size. Omobranchus may tolorate and may even prefer brackish or freshwater areas. Provide a diet of meaty and algae based foods, if sufficient algae is not present supplementing with algae based foods is necessary. Omobranchus are benthic and spend quite a bit of time sifting through substrate hunting for copepods and rotifers. May pick at small sessile invertebrates. Most Blennies lack or have very small swim bladders. Be sure to provide an aquarium with a tight fitting lid as Blennies may jump.

The Oyster Blenny is also known as the Brachiosaurus Blenny. Occasionally seen in the aquarium trade. Oyster Blennies have an overall olive green color, black spots and blue to black stripes on their sides with wavy thin pale lines on their heads. Males have a prominent fleshy crest on their heads and long filamentous dorsal fin rays. Oyster Blenny can grow to 3.5".

We recommend a minimum aquarium size of 30 gallons or larger for this species.
