Hi Tory, and WELCOME to TRT!
Our two percs live in our yellow polyps.
I would like to kindly recommend that you not get an anemone.
They are very hard to keep alive and healthy, they move around trying to find better light, knocking things over in the process, they often get sucked into powerheads, and they have very specific lighting and food requirements. Anemones in the wild live for a vast number of years. Anemones in tanks generally last less than a year, often just a few months, about the time it takes for them to finish dying, a process that often has started before they are purchased.
Clownfish are quite happy without an anemone.
