Torch Coral, Euphyllia cristata, also known as Trumpet Coral, is a LPS coral with feeder tentacles and rounded tips. Colors vary widely ranging from yellow, red, brown, and green. There should always be plenty of space between the Torch Coral and other corals or inverts as it can be aggressive with its tentacles. They thrive best with moderate lighting and moderate waterflow. The Torch Coral is popular, and for good reason as it is incredibly beautiful.
