Wow, very cool, curoious how much that set you back....
Same family as Bluethroat, Crosshatch, and Sargassum. They are Pelagic (open ocean fish), and are caught in very deep water, thus the expensive price. In talking to the folks at wetwebmedia about my Sargassum, the key is getting them to eat which it sounds like yours is doing, and getting them into the tank when there are not too many aggressors as they are very mellow by Trigger standards.
Good luck, would love to see pictures too.
