Taz, it's really hard to know where to begin. What would you like your pond to become again? Bullheads are notoriously difficult to control in small impoundments, like crappie, not to mention how muddy they can make a pond, but hey, it's your pond. I personally like catching BH also, but do it from many streams instead.

Perhaps the first place to start is as you did, sizing up what is in the water and correcting balances as best as you can. I don't think I would add anything yet, and adult fish, or stream fish do not usually fare all that well when moved to new ponds.

Any Pictures of the pond? Where does it get filled from? Any chance of it getting flooded?
