I don’t own one but hope this info will help you
they are non-photosynthetic meaning that they require feedings of phyto-plankton and other foods frequently. They prefer moderate to strong water flow ,and aren't the hardiest of all corals. They also appreciate a low light are for placement.
I know a couple people that have them and they build a cave in the live rock and hang them upside down in the cave to block out the light but this is not required to be done
