To start off with, are you getting a gold barred maroon, or a regular one with the white bars? I have experience with the white bars which are notorious for being the most aggressive of the clownfish species, while the gold bar is a little more passive. They are extremely hardy fish, mine was the only fish out of five to survive ich, so i would highly recommend it to a beginner. However, she did get a bit too aggressive with my tang and angel, so they definitely wear the pants in the tank. Pairs however, seem hard to come by, so get one wherever you see one. I introduced 2 or 3 other clowns, almost dying. They're rather hard to introduce one after one has been established
