XL South American Lungfish for sale/trade for LRG Aro

I hate to do this.... HATE. I think it may be time to part ways with my big lung-er :-( He's probably 30"plus, and big around as a baseball bat!! He is in a 180gal now, with large diameter flexible drain pipe. He loves it!! I'd love to trade him for a large Aro, silver or jardin. I am located in southern Wisconsin/northern Illinois, and willing to travel (a bit) to secure the right trade/sale. kwgthad@gmail.com Thanks for your time!
