Bullseye coral, not to be confused with Bullseye Rhodactis Mushrooms, is in the Caulastrea family. It is easy to care for if proper conditions are provided.
Bullseye likes low to medium water flow and is sensitive to bright light so place accordingly. It has short sweeper tentacles, but other coral with longer sweepers can be damaged if they invade its space, so leave 4-6 inches between this and other corals.
This coral will extend feeder tentacles when food is present and will grow well with twice a week feeding of meaty food like mysis shrimp. Like other LPS coral, they can absorb dissolved organic matter which provides a benefit to the reef aquarium.
