Detailed Guide to Sexing and Breeding Techniques for Kissing Gourami

Livestock Farming 0 views
Sexing kissing gourami is relatively difficult and requires careful observation. Generally, the male fish has a slender body, with a slightly broader and larger anal fin; during the breeding season, it develops nuptial coloration, with the body color changing from flesh red to purple, and it is glossy and sparkling. The female fish is wider than the male, with a smaller anal fin, and the abdomen noticeably swells during the egg-bearing period. Kissing gourami is an egg-laying fish. Although it does not blow bubbles to build a nest, its eggs are buoyant, and the parent fish have a habit of swallowing eggs, so plenty of floating aquatic plants should be planted in the breeding tank to make it easier for the eggs to attach. Kissing gourami reaches sexual maturity at 15 months and can breed multiple times a year. Kissing

Breeding kissing gourami is not difficult. Because kissing gourami are relatively large, the breeding tank should not be too small. The breeding water should have a hardness of 6-9, a pH of 6.5-7.5, and a suitable water temperature of 27°C. The parent fish can be placed in the breeding tank at a ratio of 1:1, and some distilled water can be added to the breeding tank to stimulate the parent fish to come into heat. After a chase, the parent fish begin to release eggs and fertilize them. The volume and mass of kissing gourami eggs are less than that of water, so they float on the surface, and the spawning process lasts several hours. Each female fish can lay more than 1000 eggs, and some can reach 2000-3000 eggs. Kissing gourami have no habit of guarding their eggs, so after spawning, the parent fish should be promptly removed and kept separately to prevent them from eating the eggs.

Fertilized eggs generally hatch into fry after 36 hours. Newly hatched fry lie still and do not move; after two days, the fry begin to swim and seek food. The first food should be "infusoria," and after one week they can be fed fish food. After 2 weeks, the fry should be sorted and kept in separate tanks. If raised well, the young fish grow very quickly and can look properly formed in just over 30 days.
