Tribe / Genus: Trematocarini / Trematocara

Biotope: Muddy deep-water habitats down to depths of about 215 meters, at the limit of the oxygen-bearing layer. Likely migrates to somewhat shallower water during the night.

Typical adult size: Average length reported about 12.5 cm for females and 11 cm for males.
Sexual dimorphism: Males have a large black spot on the dorsal fin surrounded by a white halo; the marking is much smaller in females. Females are reported to be larger than males.
Diet: Feeds on small snails as well as insect larvae and crustaceans.
Breeding: A ripe female was reported with 120 eggs, about 2 mm long.
