You can do both together. You might want to get the anemone first and let it settle in. I have a pair that I use when I get ritteri anemones in to help them settle in. I'd give them to you if you weren't 1/2 a world away, lol. I can't remember where I even got that pair, Bali or The Philippines. Do be forewarned, they can be miserable bastards in a tank, especially if they're going to be wild caught. These 2 will charge the glass if they're guarding eggs and they have no issues making me bloody if I go to take their anemone. The occys that M had were the same way, but this percula pair is just insane.
