Kathy,
Mine spawn every six days, if the spawns are 2 days apart I conbine them, my old pairs clutches are about 700+ eggs, this week I confused the maroon hatch with the dottys, had to set a tank at 11pm to move the clowns, and the dottys hatched in the tank it took two days for the larvae to rinse off through the overflow.
They ussually keep away from each other, and get together to mate when he keeps her in the den until done, if she comes close to the den he chases her, some of my females look pretty beat up but they recover.
In the case of the neon , David is right, you must have a cover the aggression is more intense but she will survive if you provide shelter, i had a pair when the male ripped the female in half just after mating.
I don't know how to establish a pair any othe way only with the two juvies technique it works for me.
I have 11 Neon Dottybacks I will be selling soon but they are perhaps the first ever neons raised in a basement/house operation so I will sell to selected breeders.
