Hi C.W.
My son put feeder goldfish (about 200 of them ) in our pond last weekend. Our pond is new - only a year old this month. We have about 100 or so bluegills which have spawned - one large koi - numerous painted turtles - frogs - and 5 largemouth bass ( 2 of them are about 4" and the others about 6". There are alot of creek chubs in the pond too, which also have spawned. I didnt want the bass in the pond as I did not have an established food chain, but my son just couldn't wait to see those bass in the backyard pond. Anyway, he did put the feeder goldfish in, and in a matter of seconds - the bass were churning the water up after them. The next day I found about 30 of them in the shallows hiding in the water irises. We also put in about 200 minnows or shiners. I havent seen any of them. I think the bass the bass were very hungry. We plan to put in more minnows, and perhaps more goldfish as we can see them easier ie how many are left. I hope next year we can put in some flat head minnows and get our food chain establisehd. We live in northern Ohio. Hope this message helps. Kay
