The predators are dependent on the prey and the prey are dependent on the water quality. Measure the water clarity with a home made sechi disk. That will tell you something about the planktonic base of the water. That's pretty key to the whole works. The disk should disappear at 18 to 24 inches. Do that and report back.

Good recommendations from Cody.

Can you stock tilapia?

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
