Male and female identification and reproduction of kissing fish
It is difficult to identify the male and female of kissing fish, so it is necessary to observe carefully. Generally speaking, male fish have a slender body and a slightly wide gluteal fin. During the breeding season, marriage color will appear, and the body color will change from flesh red to purple, and shiny. The female fish is wider than the male fish, the anal fin is smaller, and the abdomen is obviously enlarged during the egg-bearing period.
Kissing fish is an egg-laying fish, although it does not spit bubbles to build nests, but its eggs are floating, parent fish have the habit of swallowing eggs, so more floating aquatic plants should be planted in the breeding tank to facilitate egg attachment. Kissing fish enter the sexual maturity period for 15 months and can reproduce many times a year.
It is not difficult for kissing fish to reproduce. Because the kissing fish is large, the breeding tank should not be too small. The hardness of the water for reproduction is 6-9, pH 6.5-7.5, and the suitable water temperature is 27 degrees Celsius. Parent fish can be prevented from entering the breeding tank at the proportion of 1:1, and some distilled water can be mixed into the breeding tank to stimulate parent fish to be in estrus. After a chase, the parent fish began to ovulate and fertilize. The volume mass of kissing eggs is smaller than that of water, so it floats on the surface and the spawning process lasts for several hours. Each female can lay more than 1000 eggs, some of which can reach 2000-3000 eggs. Kissing fish do not have the habit of protecting eggs. After spawning, the parent fish should be fished out and raised in time to prevent them from eating their eggs.
Generally, the larvae can be hatched after 36 hours of fertilization, and the newly hatched larvae are dormant and motionless. After two days, the larvae begin to swim for food. They should be fed with "migratory water" for food, and can be fed to fish and insects a week later. After 2 weeks, the larvae were screened and reared in different tanks. If raised well, the young fish will grow very fast and will be decent in more than 30 days.
