Slow day at work and my mind's been wandering. In the future, I plan to set up a large agressive fish tank with oscars, pacu, etc. I've been wondering about a native fish that grows here in Oklahoma and it seems most of the midwest and eastern states. there are several species of Sunfish, bluegill, etc. that grow here and are readily caught in any small puddle to lake sized water hole. They don't grow all that big and are probably similar in agressiveness to a cichlid or oscar. I know they can tolerate drastic temperatures since we incur 100 degree plus summers and I've broken 8" of ice and fished for them before. I can't find a whole lot on them, probably since they aren't considered an aquarium fish. I did however find their scientific names if anyone can recognize them from that. The 3 most commonly found are the bluegill, lepomis macrochirus; the green sunfish, lepomis cyannelus and the red ear sunfish, lepomis microlophus. Has anyone tried putting these in a fish tank? I know when I was younger, we caught some 2" sunfish in a sein and added them to our community tank and they were fine with the other fish being so young. The bluegill has a much smaller mouth than the other sunfish but I don't think that would be a big factor being the large mouth of an oscar. They aren't considered a game fish so there won't be any legal problems. I just figure they are much cheaper and if they did get too large (which isn't likely since the records are just over 2lbs), I can just turn them loose in a pond and catch another smaller one. thanks for any advice, Kyle
