Habitat
This fish inhabits coastal waters, including sandy or muddy bottoms in the Western Pacific, such as the Sea of Japan and East China Sea. It prefers depths from 10 to 100 meters, often near reefs or estuaries. Geographic preferences include temperate to subtropical regions around Asia and Japan.
Diet
The short-barbeled velvetchin primarily feeds on small fish, shrimp, and crustaceans, using its barbels to detect prey in low-visibility environments. It is a nocturnal feeder, actively hunting at night in schools to ambush food. Feeding behavior involves quick strikes and group coordination.
Behavior
This species is typically schooling, forming groups to forage and evade predators, which helps in open water environments. It exhibits nocturnal activity patterns, resting during the day and becoming more territorial around feeding grounds at night. Short-barbeled velvetchins are not particularly aggressive but may compete for food within their schools.
Conservation Status
