i have just setup two 4ftx2ftx18 tanks today which i will end up using to spawn them on their own and to grow up some fry. I will wait a few weeks b4 i put them into the new tanks. I have a couple of dither fish in them atm to get the cycle happening. I hope there's enuff interest in these fish as i have a colony of 3 boys ranging from 9-12cm and seven girls ranging from 5-8cm and three shells, so there could be quite a few!
