hey my grandfathers house has had a nice pond there now for the past 15 years and is full of lmb 3crapies(lol) a few bluegills and golden shiners(maybe ifthey made it without getting eatin..) I was wondering if it is a good idea to put koi in there for a food source for the bass as the bluegills have only been in there for a few months and didn't produce any babies, also I would like the koi in there because they also make the pond look good
