Xiphasia setifer Swainson, 1839
Despite its eel-like body, it is a blenny, specifically a snake goby. It is easily distinguished from other blennies by its extremely elongated body. The dorsal fin begins above the eye.
Adults are found in open soft bottom and mud habitats, from shallow bays to deep water. They are found in tubular burrows in sandy or muddy soil. They are rarely seen during the day as they look for food at night.
The stomachs of two specimens fished at depths of 50–54 m off the West Indies contained crustaceans (including copepods), remains of bristleworms, foraminifera, fish scales, and some sand and mud. Oviparous.
The spawn consists of ground and adhesive eggs, which are attached to the substrate via a thread-like adhesive pad or base. The larvae live planktonically and are often found in shallow coastal waters.
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!
