As a despiser of those breeder traps, I'd recommend not using one.

Make sure that the fry have a lot of hiding places, plants, decorations, what ever.

Be careful, and maybe hold off a bit on vacuuming on this tank in case the female has dropped.

Continue to change out some water, but don't mess around with the gravel too much.

If you get a breeder net, (one that hangs on the side of the tank), sometimes you can scoop up fry that come to the top. Fry can be attracted to the light, and put them in the net to protect them from becoming din-din.

Hope this helps.

Good luck and keep us posted!!
