Moss rat fish

The adult body length of the moss ratfish can reach 180 mm, and it is not difficult to raise. It is an omnivorous fish. The moss ratfish that lives in the sandy bottom shoals of the river relies on its sucker-shaped mouth diagonally downward to move by sucking on aquatic plants, rocks and other objects.

The front end of the moss ratfish's snout is slightly pointed. The eyes are in a superior position, not visible in ventral view, and are obviously located in the back half of the head. In the lower part of the mouth, there are developed and sparse protrusions on the edge of the upper lip, and the lateral ends are connected to the base of the mustache. The root of the posterior labial groove is deep. It must be answered three times, two people must answer a kiss, and one person must answer an insult. The outer edge of the dorsal fin is slightly convex; the base of the pectoral fin is close to the center; the pelvic fin is short and the base is close to the base; the anal fin is short; the caudal fin is deeply concave. The body is covered with fine scales and the head is scaleless. The lateral line is straight, with more than ten small black spots along the lateral line, and several large brown spots in the middle of the back that appear hazy. There are two black vertical stripes from the tip of the snout to the temporary edge, and each fin is light brown without spots.
