Right now my 3rd pond only has FHM, LCS, and spotfin shiners, but very few plants. If I had a few more plants, I think that pumpkinseed would have a good chance of doing well. This 0.4 acre pond has very little watershed and is primarily spring fed, so I think it has low fertility right now. There seem to be quite a few very small fish in it though, so they must be eating something. I need to spend some time seeing what is in nearby streams.
