Hello. I'm planning on breeding clowns. But I want to know how to breed my own rotifers so I'll have a large food source. I read something about taking a half boiled potato and putting it in a jar will grown them. But is this saltwater rotifers. If anyone has any idea as to how to grow saltwater ratifers please help me. I'm planning on taking water out of my tank into a jew to get them started but I have no idea what I'm doing and I need these ASAP to feed the clownfish fry...
