One of my favorite micro fish, I used to keep and breed these guys. Tons of fun and pretty easy to breed, the adults love microworms and that's one of the best ways to get them breeding, I fed the new babies APR, but golden pearls would probably work just as well.
Plants are great for them, moss is a plus for breeding.
We've got some at Midway, APFP has them and Blue Sierra had them last time I was there.
