OMG, thanks for all the responses!!
After reading through all the input, I would LOVE to get the widebar, but noticed they can get up to 24 inches! I don't even think my 150 Gallon tank in the living room would be sufficient to keep him in with all the other fish.
I just got a new 75 gallon tank for my bedroom, and have no problem getting a bigger tank in the future... however, for space reasons in the bedroom, I would rather not go larger than 100-120 gallons.
I have decided to go with the thinbar's.... thanks for all your input guys (and gals).
If you see any for sale, please be sure to let me know. Before I posted this thread I did see the widebar, and was highly interested in that one, and the thinbar's I saw for sale are already sold... so unfortunately, I'm out of luck with the finds I thought I had.
Great site, awesome input guys!
