Russ :

Thanks for the great report. It sounds like the BG pond is doing well. If those are GShiners they should help a little with BG #s control by eating a few eggs and fry. I to enjoyed Dave's PS to RES comparison. If you can control the tendency of both the BG and PS to overpopulate and stunt you should have an interesting combo of fish. Here is a pic of a BG x PS from Wisc. Fish ID.
