When I want a mating, I never do anything special.
Just plop a female I choose in with a male i Pick, watch them for a min to make sure their gonna get along.,
I pretty much walk away and remove the female 12 - 24 hours later, I ignore the male other then feedings for about 2 weeks, Then I see fry swimmin everywhere,
The more I fretted and worried about doing something wrong, the more failures I had,
So I stopped fretting and just let nature do its thing, And wahlah tons of babies.
I got babies now from a mating several weeks ago, Their still with dad and will remain so until they are much much bigger.
So no I guess I really have no trick or tips,
otherthen keep the tank full of floating plants, javamoss and algea growth on the walls, and the babies do fine until big enough that I can see then, which is about 2 weeks.
