I have a small AIO that I think I'm going to make into a copepod breeding tank. I want to try to keep a healthy population going, just to add to my reefs. So if I can be successful with that, then I'm one step closer to trying to raise fry one day.I highly recomend raising live foods first. This will help you in the long run. What you raise, be it copepods or rotifers, you can feed to your reef tank. That's what i did with my live foods that I didn't need. You can never have too much practice culturing live foods
