I've had one for 5 months so far. Seems to be doing fine. I was really worried about swim bladder disease when I picked him up, but he seems to be doing just fine. Hopefully he doesn't develop it.
It's a really cool fish. I like their body shape and behavior. Be sure you have a secure top, though, or you'll have a grouper jumping at you every feeding. The second food hits the water, mine launches himself at it. I have to be quick in closing the lid or I get splashed pretty bad.
I think 125-200 is a good price for one.
Reefer334, how long did it take yours to develop the disease?
