I would add fatheads and/ shiners if you add any minnow type forage at all. But bluegills will spawn more than once and should rebound.

Shad depending on the species could be a very bad thing. Threadfin shad if you are far enough south, maybe. Gizzard shad in a small pond I would avoid like the plague. Up where I'm at they compete with bluegills and quickly get too big for forage size even in some of our larger lakes and reservoirs.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
