My maroon is pretty big (had her for over 10 years). Her beau is small, though, as is the Cinnamon's beau... The momma Cinnamon is not as big as the maroon, but is decently sized. The Cinnamons don't leave the anemone very often, but Shakes leaves hers from time to time, but never goes more than a few feet. This will be the primary decision maker on whether or not I consolidate tanks into a larger one...
