I currently have a 180 AGA with a 6" Naso that I love. He is doing well and still growing, although I know that they do grow slowly. I may be forced (circumstances beyond my control) to downgrade to a 90 AGA (48"W). I know it is not ideal for him, but is anyone out there doing something similar. My wife and I live him and do not want to get rid of him, but I also do not want to unfair him. Any advice would be great.
