Info

Eviota irrasa Karnella & Lachner, 1981
Unpolished dwarfgoby

Inhabits rocky and coral reefs.

Main reference: Karnella, S.J. and E.A. Lachner, 1981. Three new species of the Eviota epiphanes group having vertical trunk bars (Pisces: Gobiidae). Proc. Biol. Soc. Wash. 94(1):264-275. (Ref. 5289)

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!
