Thanks for your further opinion Wiggles....I've had the grey guy for about 3 years...got him at maybe 8-10" from T.F.D. (Tropical Fish Distributors) for $40 steal IMO. He's now 20" Its decieving because hes in a 650gal and looks way smaller lol. Tank is on cinders though and he exceeds the 16" blocks when he sits in front of the tank. Brown guy about 14-16" came from a good friend and fellow MFK in garettsville ohio a year ago maybe? for free. I'm pretty sure he got it at RMS up in cleveland ohio. Never been there myself. Are you tracking where the diff. species are hitting? this could be interesting...I have seen a similiar lung to my grey WAL in pittsburgh. same orange around the head. they wanted crazy prices for it though. personally i love the grey color variation alot more than the brown just my opinion though.
