hi guys, had a quick trawl around on google, and i know these things do breed but how easy is it? any tips on doing this apart from feeding more with high protein foods.. also, if i want to have these in my tank, is it best to have 2F to 1M? how do you tell the differance? (is it that the males are more coloured?) - it will be hard to tell in the LFS where all their fish are only 50% coloured up.
