Scientific name: Ecsenius lividanalis
There are two varieties of the Black and Yellow Blenny. One variety has a predominantly blue head contrasted by a yellow body and yellow iris. The second variety, known as the dusky form, is more pale blue in color with a yellow dorsal fin and a pale blue or white iris. There is also a rare variant of the dusky form which is all yellow. A common feature to both varieties is a black anal spot.
This is generally a peaceful species of Blenny. However, it is ideal to keep only one per tank. These fish are known to nip on clams and stony corals. Black and Yellow Blennies may act territorial towards other Blennies or similar species. These are reef-compatible fish and often hide in crevices or perch on rocks.
This species requires a tank of a minimum of 30 gallons to thrive. These are reef-compatible fish and need live rocks and corals to dart around and hide in.
