Bicolor Blenny

(Ecsenius bicolor)

Ecsenius Blennies are sometimes referred to as Clown Blennies. Blennies should be added to well established aquariums. Rock work should be provided for perching, hiding and grazing. Ecsenius Blennies are considered to be easy and peaceful however, can become aggressive to other fish resembling their shape. If sufficient algae is not present supplement with algae based foods and algae matter. Males tend to be larger than females. 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 Bicolor Blenny is also known as the Two Colored Blenny. Commonly seen in the aquarium trade and have a great personality. Bicolor Blennies have an interesting blue to brown color on the front half of their body and a yellow to orange back half. Bicolor Blennies can grow to 4".
