My brother caught a 10 in. long and 6 in. tall bluegill from a small lake called Rancho Seco. The bluegill is the biggest I've seen in person and I brought it home and I'm trying to keep it alive. It's in a tank with some other bluegill, carp, and baby bass. I try to feed it some blood worms and red worms but all the other fish get to it first. Even when I put a small feeder fish in the bass attempt to swallow the feeder even though the feeder is half the size of themselves. My brother caught the bluegill on a fly fishing bait. What can I do to make sure he is well fed? Any good fish food or insects that will satisfy his appetite?
