Congo tetra ratio and breeding

[Plutoids Mom]

I just caught a pair of my congo tetras spawning in my community tank! Was totally unexpected because I thought they were hard to breed but mainly because I had bought a group of six juvenile males. My main question since I now know that at least one, maybe two, are females, should I try to find more females so they don't get too harassed by the four or five males? They have all been growing at different rates, so I for awhile I thought I ended up with just two males.

On a side note, I have larger gravel and a decent number of other fish in this tank. I'm assuming there isn't a chance the eggs will hatch and the fry will make it?

I think you would be better 2females to 1male for breed Congo tetras
