Clowns in general live either alone or in pairs. What you are probably looking at is a mated pair. They will live together but you cannot have anymore clowns. As far as having one anemone. It depends on the female clown (bigger of the two). She may or may not allow the male in but this is assuming they even decide to host the anemone. This isn't really a problem if she doesnt let him in. He will submit to her will and just hang out around the tank.
Actually IIRC, many species of clownfish live in groups in anemones, not solely as pairs and such
Also, it may not be a mated pair quite yet (unless you see them laying eggs. It could very well be just a bonded pair. Big difference IMO, as this can affect price significantly. It is not uncommon for clowns are sold as either bonded, or mated pairs.
Females do tend to wear the pants in the relationship, and keep the male in a submissive position most times. She will reassert her dominance from time to time, which is normal. How big are the maroon clowns, and how big is the anemone when fully opened? You want to be sure that the anemone can physically accommodate the clownfish. If the anemone is too small it is very possible for the maroon, or maroons to pummel the anemone to death. Maroons do have the tendency to go straight into BTA's as they naturally occur in this manner, though it is never really quite guaranteed it will happen (immediately anyways).
