They are easy to care for. They dont like too much light or flow about medium on both. All corals like to be fed not sure exactly about these. I am getting a wellsi and have read about them from aquarium corals by eric boreneman. They would probably take mysis or zooplankton
I have a large rock full of them as well as one single about four inches big in my seahorse tank. They get some mysis shrimp when I feed the horses and close up around it. They also get phyto and cyclo. But they seem to close up most with a half shrimp.... HTH
