From what I've heard it's one of the easiest egg-laying fish to breed, as fry don't require any special care, just crushed regular flakes for food. You'll still need a separate tank for spawning, because the parents eat the eggs and fry. I've accidentally bred 3 babies in a common tank, but that's not much. From what I've observed, they spawn in mornings and then calm down around noon, so I guess you'd need to move them accordingly.
