Breeding tetra fish allows you to produce more red fins or neon colored characins for your aquarium. You may also be interested in selling these as pets to other persons. If you want to breed them, you will have to get a separate tank for that purpose. This should be set up with moss and plants to make it comfortable.
Once you’ve created the ideal setting, place the female tetra in the aquarium so she can check it out. As she gets accustomed to her new environment, she will become more relaxed. This is important if the mating is to be successful. She will also need her rest. Make sure that you put a fat female characin in the tank.
Check to ensure that the tank has fine leaved plants that can catch the eggs later on. Humans are not the only ones that are sensitive to the look of their environment. These fish prefer soft, relaxed lighting when they are breeding. You should also check the pH of the water to ensure that it neither too acidic nor alkaline. A pH of 5 is ideal.
Place the male in the tank after her. He should be the one that has colors that you like best. They will engage in a little cat and mouse game for a while, until eggs are laid. Young fish will emerge from these eggs within a day. Once eggs have been produced, many breeders remove the adults from the tank to stop them from eating the eggs. The fry are fed foods such as infusoria.
