Info
Unfortunately, we do not currently have access to the initial identification of this goby, but can contribute some information from a finding report of the species from Japan.
Hazeus profusus is found in larger aggregations on sandy mounds on sandy bottom habitats and muddy bottom slopes.
As can be seen well in the picture, they goby with its body coloration quite well adapted to the bottom.
The specimen found in Japan was collected alone at a depth of about 10 meters on a steep sandy-muddy bottom slope extending from 5 -3 0 m depth in the inner bay of Amami-oshima Island.
Brief Description:
The present specimen possessed 10 dorsal-fin soft rays, 9 anal-fin soft rays, 17 pectoral-fin rays, 13 branched caudal-fin rays, 26 scale rows in the longitudinal row, 8 scale rows anterior to the dorsal fin, a completely scaled cheek and operculum, ctenoid scales covering the body, nape, operculum, and posterior part of the cheek, cycloid scales covering the area anterior to the pelvic fin, pectoral fin base and most of the cheek covered, the first spines of each dorsal fin are strong, the second dorsal fin spine is not elongated, 2 longitudinal and 5 transverse rows of sensory papillae on the cheek, 5 large dark spots on the middle of the body, the first dorsal fin has no large black spot behind, dark bands on the snout, cheek and behind the eyes, and dark and white spots on the upper and middle part of the pectoral fin base, respectively.
Etymology:
The species name "profusus" probably refers to the English word "profuse", meaning "abundant", referring to the fact that the gobies seem to have a preference for sand accumulations / sand mounds where they are then found in groups.
We sincerely thank Jim Greenfield for the first three photos of this species!
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!
