Combtooth Blennies of the Genus Ecsenius

By Bob Fenner

Ecsenius stictus

     The genus Ecsenius deserves special attention in the family Blenniidae; with forty seven species these are delightful, small (to four inches) fishes that do superbly well in peaceful fish, invertebrate and reef systems.

The quintessential member of the genus is the Midas Blenny Ecsenius midas, with changeable yellow, purple, brown and pink & blue. The Midas is a good assay organism as they exhibit rapid and extreme color changes when stressed. Considered to be a mimic of the Coralfish Pseudanthias squamipinnis among other Basslets over it's wide range, this little beauty is very un-blenny-like in its disposition to stay out from cover hiding amongst its adopted "school".

Two other favored Ecsenius are the orange and purple Bicolor, E. bicolor, and the gorgeous yellow and blue E. gravieri.
