Trimma longispinum Winterbottom, 2023
A new species of Trimma is described from Tabuaeran and Kirimati Atolls, Kiribati (formerly known as Fanning
Island and Christmas Island in the Line Islands, respectively). Trimma longispinum is characterized by a scaled
predorsal midline, the fifth pelvic-fin ray with one dichotomous branch point, 6–9 branched pectoral-fin rays,
the bony interorbital 30–42% pupil width with the posterolateral trench not reaching papilla p 6, no opercular
scales, and 8 or 9 anal-fin rays. It has 6 papillae in cheek row c, an elongate second spine of the first dorsal fin (to
the middle of the second dorsal fin or farther posteriorly when abducted), and a color pattern with red to yellow
saddles adjacent to the dorsum and on the anal fin and across the caudal peduncle. The species is also present off
Sand Island, Palmyra Atoll about 370 km to the north-west of Kiribati, as well as possibly at the Marshall Islands
(Eniwetok Atoll), and Guam (Mariana Islands).

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!
