I have a couple of maxi/mini, 4 Rock Flower and a Rainbow BT. They all just found a spot and kicked their feet up. I don’t do anything special. I feed the tank and they do the rest
I had a carpet anemone and loved it. It grew big eventually. I would feed it some squid or other meaty food occasionally. If you have the right clowns they should love it. I had a maroon clown at the time and he did.
