It's what I started my system with. I bought the "feeder" kind from one of the big box pet stores for $0.27 each. I would even get a $3 coupon for taking their online survey and got a bunch free. I also started a warm farm and have been feeding the blue gills from it. The gold fish will be too slow to get the first worms of the day but when the blue gills slow down, they finally get theirs.
