I've got both of those fish in a tank with a couple goldfish. This morning I threw a few worms in for the goldfish.. didn't really expect the redspotted sunfish or the other one (I think it's a green sunfish.. it's got some nice color in the tank) to eat so I didn't bring enough worms for them. Well the little one grabs a worm and starts eating it and the big one grabs the other end and they start tugging. Big one wins. Then it went and ate another worm before the goldfish could get to it. I guess I know what to feed it.
