Sometimes they work upside down, sometimes they are busy, they swim to the surface quickly, and they use their unique auxiliary breathing organs like other betta fish to directly breathe the air directly on the surface of the water, although the kissing fish is so busy , but it is still not a good aquarium scavenger, because although they like to eat algae, it is not their staple food. Kissing fish eat a lot and can accept any bait. Eating algae is just its natural nature and supplement it. It is active and consumes a lot of physical energy.

But this fight is not fierce, as long as one side backs down, the victor will not continue to chase and fight, but will continue to immerse himself in its cleaning work, as if nothing has happened. Therefore, their gentle habits do not pose a threat to any other fish, so they are suitable for mixed breeding. The body length of kissing fish is generally 20 to 30 cm. The body is oblong. The head is large, the mouth is large, especially the lips are thick and large with fine serrations. Big eyes with yellow circles. The dorsal and anal fins are particularly long, extending from the rear edge of the operculum to the caudal peduncle. The pectoral and pelvic fins are fan-shaped, and the caudal fin is normal.

After the eggs are over, the fish should be fished out immediately to ensure the number of eggs. In addition, since the number of eggs laid by kissing fish is generally more than 1000-3000 according to the size of the species, and its eggs contain a lot of oily substances, it is easy to cause water pollution and affect the hatching survival rate of fish eggs, so it is necessary to improve the water quality immediately. .
