Tomiyamichthys tanyspilus is a guard, symbiotic or partner goby, i.e. it lives symbiotically with a crayfish.
The crayfish is responsible for building the burrow and the goby is responsible for guarding the entrance to the burrow.
If the goby notices danger from an approaching predator, it signals this to the crayfish and both partners disappear into their refuge in a flash.
Etymology:
The name of this species is "tanyspilus" from the Greek "tany" for long, and "spilus" for spot, in reference to the elongated shape of the 5 central dark brown spots on the body.
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!
