It doesn't really seem like any mating happened because there haven't been any eggs for 2 days now. I don't have any leads to what caused their excitement.
Ses, the pictures would be great! Thanks for all the info. Just one question: A breeder's net, you mean like the ones you stick into the tank that have the covering as a net?
Also, i can't exactly say so right now since they're young, but they all appear to be males
. So i'll have to wait and see how it will end up.
