Ecsenius lividanalis

Ecsenius lividanalis, commonly known as the Blackspot coralblenny, is a tiny blenny. There are multiple colour forms which might get separated in distinct species in the future. The original description is of a yellow fish with a blue head. But this variant is seldom encountered. Then there is a totally yellow form and a dusky blue form. This last variant is the one we usually have and when mature it will develop yellow fins. All variants/colour forms have a black anal spot.

These fish are usually found in small groups, on, or around coral. In an aquarium be sure to have rocks with small holes they can hide in before introducing them. In a large aquarium multiple blennies is possible as long as enough territories can be formed, but in a nano tank they can best be kept alone or as a proven pair. They feed mainly on zooplankton and can best be fed with live and frozen food like copepods, artemia and small gammarus, but usually will learn to feed on high quality flakes and pellets as well!
