How Do Neon Tetras Breed? A Detailed Guide to Breeding Methods and Techniques
The neon tetra, also known as the red neon tetra, neon light fish, red-green neon tetra, red light fish, and so on, is covered all over in a blue-green glow, with a bright blue-green band running from head to tail, a red band below the blue-green band on the rear half of the body, and a blue-white belly; the red and blue bands run through the whole body and are dazzling to behold. Let us take a look below at how neon tetras breed!
Neon Tetra Rearing Environment
In the wild, neon tetras mainly inhabit the blackwater and clearwater areas of the Solimoes River in South America. Their habitat has a typical tropical rainforest climate, hot and rainy all year round, with temperatures between 20-26 degC, pH between 5.0 and 7.0 (on the acidic side), and GH between 1 and 2. It is best to keep them in soft water, but after many generations of captive breeding, they can also tolerate the hardness of tap water.
Distinguishing Male and Female Neon Tetras
The main way to distinguish male from female neon tetras is that the male's body is more slender than the female's, with a pointed tip at the end of the anal fin and darker coloration. During the reproductive period, the female's body is plumper, the anal fin is fan-shaped, and the body color is lighter.
How Neon Tetras Breed
Neon tetras reach sexual maturity at 6 months of age, and 8-10 months is the best breeding period. When the female's abdomen swells, keep her separate from the males for a few days first, feed her well, and then pair them up in a tank. The breeding water requires a pH of 5.6-6.8, GH of 1-3.5°, and a water temperature of 25 degC, with an artificial spawning mop placed inside; the breeding tank must be shaded from light and kept quiet. One female can lay about 150 eggs. After spawning, remove the parent fish to prevent them from eating the eggs, and the fry hatch in 24 hours.
Managing Neon Tetra Fry
Neon tetra fry are tiny and swim only a little, and can only feed once the food reaches their mouths. For the first food, sieve egg yolk water through a 200-mesh net and feed it drop by drop with a pipette; after some time, when the fry are swimming normally, switch to egg yolk green water sieved through a 150-mesh net. The fry grow slowly and feed on egg yolk green water for longer than other small species. In addition, the water in which the fry hatch is extremely soft, and the water temperature is completely different from the usual rearing water temperature. When the fry grow to 5 mm, they must be moved to a large tank for rearing, and care should be taken to let the fry go through a process of adapting to the water quality.
