Neon tetras are one of the most popular types of fish that are purchased for home aquariums. They are small and brightly colored. They are very prolific, and a pair will create hundreds of eggs. They do not engage in caring for their eggs or babies. Many of the eggs fail to develop or are eaten, as are the tiny baby neon tetras. Perfect water conditions and a separate aquarium will help you in breeding neon fish.
Instructions
1. Set up a breeding aquarium. This will reduce the chances of illness to the eggs. Make sure that the separate aquarium has a lid, because neon tetras can jump out. Set up 2 to 3 inches of rocks at the bottom and add in aquatic plants. The water should be below 75 degrees Fahrenheit. The ideal hardness for the water is below 4 degrees, or pH of 1 to 2.
2. Get a pair of tetras for mating. Choose young, healthy fish to increase your chances of successful breeding. Females have larger bellies. Males have a straighter blue line.
3. Move the mating pair to the breeding aquarium. Feed them live food, which will help induce spawning. Many professional breeders use mosquito larva. Keep the amount of light that reaches the aquarium limited; the eggs are very sensitive to light.
4. Remove the breeding pair as soon as they spawn, which usually happens early in the morning. This will prevent them from eating the eggs and baby fish. The eggs will be small and transparent but will become free-swimming baby fish in three to four days.
5. Feed them only small amounts of food during the first few days. After one to four weeks, they will be large enough to consume foods such as brine shrimp or bits of beef liver. After a month, their adult coloring will appear.
