Info
Dr. Ross Robertson has discovered this particular small three-fin blenny, Enneanectes exsul, around the Revillagigedo Islands, here more specifically around the islands of Isla Socorro, Isla Clarion, and Isla San Benedicto, in the eastern Pacific Ocean.
The Revillagigedo Islands are an archipelago that belongs to the Mexican state of Colima .
The small fish had a mirror egg-like patch of ctenoid scales on the operculum, and an enlarged scale covering upper 2 / 3 of the pectoral fin axis.
Around the nasal bones are a series of small spines on the second dorsal fin is a dark distal spot.
The first dorsal fin has the namesake "three spines"; the second dorsal fin has 12 spines; and the third dorsal fin with 8 - 9 pieces.
Anal fin with two spines and 15 -16 segmented rays. pectoral fins each with 15 rays.
lateral line discontinuous with 14 -16 scales in the upper part and 17-19 notched scales in the lower part.
Coloration of Enneanectes exsul is brown and yellow or cream in most dark areas.
Radiating rust colored lines run across the iris.
Between the bands on the body are light areas of brown and a yellow pigment that partially outlines the scales.
The first dorsal fin is cream and mottled brown, the second dorsal fin shows a dark spot on the membrane between the anterior spines and a strong diagonal band of light pigment in the posterior region
The third dorsal fin is similarly banded.
The caudal fin has pale proximal and distal bands, with brown between them.
Anal fin has brown and yellow banding, pectoral fins have brown and cream bands.
Etymology. From Latin "exsul", an exile, in reference to the habitat of this species on an island.
Jumping guard
A jumping guard prevents (nocturnal) fish from jumping out.
Wrasses, blennies, hawkfishs and gobies jump out of an unprotected tank in fright if their night rest is disturbed, unfortunately these jumpers are found dried up in the morning on carpets, glass edges or later behind the tank.

A small night light also helps, as it provides the fish with a means of orientation in the dark!
