I used pretty much the same method as alanmin,but a bit more ruthless,fed them up well separately,put them into a fresh tank with no gravel,just a potted plant or two.cold water turned the heater on when I put them in,next morning as the temp comes up away they go ,better with 3 males to each female,works for peppereds as well.start them on brineshrimp,microworms small daphnia,they seem to do better on anything live rather than flake etc,I suppose thats true for most?They do eat the eggs although not straight away,make sure they have finished before you take the parents out,sometimes you get huge numbers,other times can be a bit sporadic?
