Yep, you have the fever. I am always planning my next tank too! My Volitans lion is getting very big, and needs a larger tank. He is in a 125 gallon tank now. I just don't know where I can put a tank that large. I will have to do it soon, or I will no longer have a damsel, coral beauty or lawnmower blenny. I like the prospective choices you listed. I want a Harlequin tuskfish, but will need a second mortgage on the house to pay for it, LOL. Okay so I exagerate a bit, but they are expensive. Start a new post when you get that one up and running.
