Need to rehome fish

I purchased a fully set up 29 gallon saltwater tank over the weekend from a pet store that went out of business in Brainerd. There is a large fish in this tank that is way to big for it. Wondering if Anyone with a large tank would be able to take it. I am pretty sure it is a very large, very old neon velvet damsel. It is not aggressive with the other fish in the tank (pair of clowns and 2 small damsels). If someone can tell me how to post pics I can put one up. Thanks

It's easiest to post pics up using photobucket.  PM me if you want me to walk you through it.    Not many of us here in Bemidji have big tanks other than the Science Center.  It might work in there though.
