Info
The body of Enneapterygius olivaceus is yellowish-brown, with about 5 dark oblique stripes and speckled with whitish spots, while the lower half of the head and the base of the pectoral fins have scattered melanophores.
The first dorsal fin is translucent white, the membrane between the first and second stingray is cream-colored.
The second and third dorsal fins are transparent with black spots.
Distribution and habitat.
At present, Enneapterygius olivaceus is only known from southern Japan and the Philippines.
The specimens examined in this study “A new species of the genus Enneapterygius (Perciformes: Tripterygiidae) from Japan and the Philippines, with a synopsis and synonymy of related species” were collected in the southern part of the Ryukyu Islands (Amami, Okinawa and Yaeyama Islands) and on the Talampulan and Negros Islands in the Philippines.
Habitat: Animals were collected on the top of the rock covered with short seaweed, among other places.
Etymology. The specific name “olivaceus”, comes from Latin and refers to the olive-green body color of the specimens.
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!
