I've had a largemouth bass in a 600 gallon pond for 5 years. I raised the largemouth from a fingerling and he is now around 4 pounds. He looks about that, I've never taken him out of the pond and weighed or measured him. About a year ago he nearly beat my koi to death, so I had to take it out. The pond is absolutely full of breeding populations of mosquito fish and bluespotted sunfish. I recently found a brown bullhead in the pond that I put in years ago and assumed it died. I haven't added any other fish near the size of my bass because I always thought he would kill the, like he tried to do with the koi. He hasn't done anything to the bullhead so I don't know. I'd love to put a longnosed gar in there but I'm not sure how the reaction will be. My pickerel also really needs an upgrade as he is approaching 11 inches in a 60 gallon long. I'd like to move him in there but I don't know if my bass will attack him. I'm also worried he may be able to eat the pickerel.
