How Do Neon Tetras Breed? Detailed Breeding Methods and Tips
The neon tetra, scientifically named Paracheirodon axelrodi and also known as the cardinal tetra, red neon tetra, or new red neon tetra, is an important ornamental fish of the genus Paracheirodon in the family Characidae, suborder Characoidei, order Characiformes. Native to the Amazon River basin in South America, it has a gentle temperament, is best kept in groups, and swims in a lively and active manner, making it very endearing. Let's take a look below at how neon tetras breed!
Distinguishing Male and Female Neon Tetras
Male and female neon tetras are mainly distinguished by their appearance. Generally speaking, the female neon tetra is wider in body than the male, with a noticeably swollen abdomen. Although the male is narrower and more slender than the female, its colors are brighter and more colorful than the female's. When breeding, choose broodstock with a body length of about 5 cm.
Breeding Time of Neon Tetras
Neon tetra fry grow extremely quickly, reaching sexual maturity in about 5 months, and can breed multiple times a year. They usually enter the sexually mature stage at 6 to 8 months of age. They are egg-laying fish, and spring and autumn are the seasons for artificial breeding.
How Do Neon Tetras Breed?
1. Breeding environment: The breeding water temperature for neon tetras is 26°C, and the water should be weakly acidic. A layer of gold thread grass should be laid on the bottom of the breeding tank, and the tank should be placed in a dimly lit place, or the light should be blocked with newspaper or similar, leaving only a faint light. Then add a little table salt to the water and add 1/3 distilled water to stimulate the broodstock into estrus.
2. Introducing the broodstock: At dusk, place the selected broodstock into the spawning tank at night in a male-to-female ratio of 1:1. The next morning the broodstock will begin to spawn. After a period of chasing, the female lays her eggs on the gold thread grass, while the male simultaneously releases sperm over the eggs to fertilize them. Spawning takes several hours, and each female can lay about 250 eggs.
3. Incubation management: After the neon tetras finish spawning, the broodstock should be removed to prevent them from eating the eggs. The fertilized eggs hatch into fry in about 36 hours, and after another 36 hours the fry begin to swim and forage. At this time they should be fed "infusoria", and a small amount of table salt should also be added for disinfection. The fry can gradually be exposed to light, and after 15 days they can be switched to small live food, after which they gradually enter normal management.
