Some of the Tangs are really large, as are the Rabbit/Foxfaces, and there are a number of other large fish that aren't in the video.
I had 2 huge Yellowfin Tang (Acanthurus xanthopterus), close to 2' each and very thick, that I got rid out last year, unfortunately one died on the way to the aquarium.
He's in the other tank, as he doesn't play well with the other Tangs. He doesn't play well with the Triggers and Groupers either, but they can handle it.
