After my recent tragedy with my cuckoos (here), today I saw that my S. petricolas have finally successfully bred! I had given up a while back and just left them in their tank by themselves, often thinking about selling the colony off. Today during my water changes I saw two little ones darting around the tank (about 3cm), it really made my day. My setup is very similar to what other people use for breeding, an upturned flowerpot with two holes in it, sitting on marbles on top of a grate. I also have another flowerpot just sitting on top of a mat of plastic plants. So I don't know which setup was successful but I'm glad one of them was 
Very happy today
