Info
Endemic to eastern Australia
Habitat:The goby lives in protected bays and estuaries with silty sand near large rocks from the central Queensland coast and the central New South Wales coast south to Sydney.
Males usually darker than females, male genital papilla usually ending to side of anal, fmale genital papilla truncate and ending well before the origin of anal fin.
The length of anal, pelvic and 2nd dorsal fins longer in males.
Description:
Body grayish white with brown and white spots, row of double and single dark dashes along body behind pectoral fin with white spots in between, dark scale edges creating reticulated pattern on back, oblique orange marks on cheek.
Istigobius decoratus (Decorated Sandgoby) and Istigobius rigilius (Orangespotted Sandgoby) have dark double spots or dashes that are equal to or wider than white spots. Found on sand patches near reefs.
Hoese's Sandgoby can be recognised by its raised eyes, elongate body, and pale sandy to pink colour with dots and dashes.
It often has blackish lips. Like most gobies, it has pelvic fins fused into a cup-shaped disc.
Istigobius hoesei was named in honour of Australian Museum ichthyologist Dr Doug Hoese.
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!
