I can say something to neon, P. innesi.
Breed approach in the pelvis, about 30 liters. It is good when several approaches are. The bottom of the glass should be painted with black lacquer exterior. Inside should be a suitable spawning grate. I've made Glastreifen with silicone adhesive as a fitting platform and on a plastic sieve cloth mesh size approximately 1 to 1.5 mm. In the middle of a clean spawning should be plant. The water is soft (dgH6 °) and be slightly peaty. Whether the females are spawning ripe can be viewed. They chase each other.
It is good if 2 to 3 are male.
If they are desinterested and standing together, then the spawning is complete. The females are now slim.
Now the parents have to be removed. The spawning grate well.
After some time, the grains must be controlled. Glassy grains are fertilized. Unfertilised are white. These must be removed (pipette). It arises as a ray fungus that infects the good grains. The black color under the glass floor you can see it well.
When this is done by, the basin should be darkened slightly. The eggs develop. there are Larfen. then hanging around on the discs.
They have a yolk sac, which reaches about 10 hours. Then powdered food from pond must be there. The Larfen peel away and swim across the pool. It must be fed carefully. (Finely sieved). Not too much.
After a week Artemia can be fed..
