Breeding Neon Tetras- Its easy
Egg scatterer, requires soft, very clean water. Failures in breeding are in most cases due to unsuitable water conditions. To spawn them, you will need a small tank placed in a dark spot as the eggs seem to be light sensitive, a 2 inch layer of half inch rock and some bunches of fine textured live plants like Myriophyllium are suitable as the spawning medium. Only young fish should be used for breeding and at least 5 fish (with a ratio of 2-1 males) that have been separated (put the females in the tank that will be used for spawning) for 2 days and fed some live foods. The temperature should not rise above 750 (21 to 23c) Keep a lid on this container as they will jump out. Keep the breeders together for 24 hours and then remove them. They usually spawn early in the morning. The clear eggs are laid among the plants and barely stick to them. In 22 to 26 hours the eggs hatch and the fry are very hard to spot, but appear 3-4 days later at which time they are free swimming and will need to be fed infusoria. The species is not very prolific and A good spawn would be 40-50 fry.
