I agree with Tony detroit, they are very picky eaters, but if you can find one that is eating well in the LFS, that would be the one to get. The one I have is about 11inches and has the streamers growing. I feed mine seaweed selects, frozen brine and prime reef flakes soaked in garlic and kent zoe twice a day. Beautiful fish, but like tony and karajay said, they need alot of swimming room. Mine is in a 180 and it is almost to small for him. I do have another much smaller one in a 75gal (about 4inches) and he has plenty of room. But they do grow large quick. Lots of luck to you and hope this helps.
