mine breed all the time. It takes about 3 days to hatch and you will notice the female move them all to one small pile and keep and eye on them. as for food. I have had good results with just using a good quality flake food. Just take a small pinch and crush between your fingers and just let it fall in. Will basically look like flake dust but they will eat it and seem to grow fast on it. Once about a month old you can feed brine pretty easy but still offer the flake as some of them will grow faster than others.
