I just gave three 4-5 inch ones away lol Not sure if you can get anything for them. Most times, people or LFS's are trying to get rid of them usually due to their size. My main reason was not size though, it was because they are food hogs, they take all the food and the other fish never have a chance. There's not many compatible fish that are fast enough to compete except maybe the Bala sharks, they are quick.
