Who knows what this little fish is and what it eats?

This is loach seedlings. Can you feed some fish feed and beans? Wait a minute. Misgurnus anguillicaudatus belongs to Misgurnus family. Small, slender, only three or four inches. And it is round and short, with small scales under the skin, blue and black in color, and covered with its own mucus, so it is very greasy and can't be held. The front section is slightly cylindrical. The back side is flat, the abdomen is round, the head is small, the mouth is small, and the lower part is horseshoe-shaped. The eyes are small and there are no thorns under them. It must be five pairs. Scales are tiny and round and buried under the skin.
