Rock Bass are one of the most aggressive panfish. They will strike a variety of baits and lures and they will hit your bait extremely hard at times. Like most sunfish, rock bass rarely exceed 2 pounds. Rock bass as big as 3 pounds have been caught, but most fish are in the 6 to 9 inch range. Known as a very strong fish, they are very fun to catch for younger anglers. At times, rock bass can be annoying because these fish will school up in large numbers and continue to bite your live baits. On some lakes, if you fish with live bait, you may go through a couple hundred nightcrawlers a day because of all the rock bass. Rock bass feed on insects, crustaceans, nightcrawlers, red worms, spikes, wax worms and small minnows.
