Ya i have some really nice males coming up so that will be cool.
In the large tank im only going to keep males in the tank. then wheni need some more i will chuck the one i want in a tank of around 20 females.... His lucky day. then a month later i will do the same with another colour. or i will just split the females into 2 of the same colour per tank and do loads of cross breeding. just to see what i get.
