Extended data:
Turtle back perch is a small fish of Percidae, which is a perennial, solitary, diurnal, omnivorous and carnivorous primitive freshwater fish. Adult fish and juvenile fish are free-swimming animals near the water surface, mainly preying on small aquatic animals, including earthworms, insects, small fish, duckweed and some fresh aquatic plants. Perched in still, slow-moving muddy water.
When the living environment is polluted, the water quality deteriorates and stinks, and other fish can't survive and die one after another, this small fish still lives tenaciously, but it doesn't like living in polluted water. Every time after heavy rain and rising water level, fish will collectively climb ashore to find a good new environment to live in.
Often rely on swinging gill cover, pectoral fin, turning over and other methods to climb over river banks and slopes, move to new waters, or lurk in mud.
