Neon swallows can be bred, and it is not difficult to reproduce. Use empty tanks. Neon swallows should be selected as large and brighter as possible. Put in three or four pairs to breed in clusters, and put a bunch of buoyancy. A small nylon cloth mop to the empty cylinder.

If it is the peak breeding season, change a twig every day or every other day. If the eggs are large, they can be picked and placed in a small container to hatch. The water used for hatching can be mixed with some fungicides.
