Trimma yoshinoi: by KORECHIKA YANO, JAPAN
The new species Trimma yoshinoi is described from five specimens, 18.4–21.4 mm SL, collected in 36 m depth at Iriomote-jima Island, Ryukyu Islands, Japan.
Trimma is an Indo-Pacific gobiid fish genus, comprising cryptic, tiny (seldom exceeding 30 mm SL), colorful,
tropical species found on coral and rocky reefs, usually at depths shallower than 50 m (Winterbottom & Hoese
2015). According to Winterbottom (2011), Trimma can be recognized by having the following combination of
characters: lack of cephalic sensory canal pores; much reduced cephalic sensory papillae pattern; wide gill opening
extending to below the vertical limb of the preopercle or anterior to this; lack of bony spicules on the outer gill
rakers of the first gill arch; fewer than 12 dorsal and anal-fin segmented rays; and a fifth pelvic fin ray that is equal
to or more than 40% the length of the fourth pelvic-fin ray.

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!
