Anthias need alot of room to swim ... some say even more room than Tangs and a 33G is definately on the small side for both species ... also they require feeding at least 3 times a day so you would have to be sure that your filtration can keep up with the byproducts of heavy feedings.
A mature tank is preferred for a anemone < 6 mos to a year old > ... best bet is to wait a little till a split shows up locally here in the buy/sell section.
