it's cool to raise baby fish. The problem is those darn breeding traps!!
Although they often work, they also have a tendancy to stress the mother fish to the point of death. I don't mean to scare you but the aren't the safest. Really, the safest way to save the babies and the mother, is to provide her with a small tank half filled with a plant such as java moss. After the blessed event she can be removed back to her old home. Bear in mind that in order to raise these baby fish, you're going to need to provide enough space for them to grow.
