Kissing fish is also called kiss fish, kiss fish, peach blossom fish, big white peach, kiss fish, kiss fish, kiss fighting fish, etc., and its body color is light red. It is famous that fish like to "kiss" each other. Not only heterosexual fish, but also homosexual fish, have the action of "kissing". The kissing of kissing fish is not a sign of friendship, but a kind of struggle.
The body length of kissing fish is generally 3-5 cm. The body is oblong. The head is big, the mouth is big, especially the lips are thick and big, and there are thin serrations. Big eyes with yellow rims. Dorsal fin and gluteal fin are particularly long, extending from the posterior margin of gill cover to the caudal stalk, and the middle of the posterior margin of caudal fin is slightly concave. The pectoral fin and ventral fin are fan-shaped and the caudal fin is triangular. The fish body is oval, generally milky white or light pink. Each fin is transparent and slightly silver.
Kissing fish like to live in tropical rivers, and it is often used as an edible fish in its origin. It does not have strict requirements for water quality, is not very gregarious, swims very slowly, looks graceful and generous, and has charming charm and ornamental value. Usually, the temperament is extremely docile and lively, so it is not appropriate to mix with tropical fish that like quiet. It likes swimming at all levels of the water, but it often stops at the bottom of the fish tank when resting. Kissing fish has a variety of feeding habits. Although it is a large species, it is generally not interested in large water fleas, and it is often a long time to open its mouth to eat some small water fleas to get full. This is also a special feeding method for tropical fish. When raising, I also like to suck the moss on the walls of food boxes and aquatic plants with thick lips, so when raising fish, I often put a kiss fish in each box as a scavenger.
