The Caulastrea Candy Cane Coral is a large polyp stony (LPS) coral often referred to as the Trumpet, Torch, Candy, or Bullseye Coral. Its genus name, Caulastrea, comes from the Latin kaulos (stalk), and aster (star) describing its skeletal structure consisting of tubular stalks with stars on each tip. The plump circular polyps are vibrant green, yellow, or blue and brown, with the Candy Cane Coral from Tonga being a brilliant translucent green to teal and brown, and each tip is white. Under actinic light its colorful polyps will stand out from most other corals.
It is hardy and a relatively peaceful reef inhabitant, with very short sweeper tentacles. It requires moderate lighting and moderate water movement, along with the addition of calcium, strontium, and other trace elements to the water.
It will benefit from additional food fed weekly in the form of brine shrimp or micro-plankton.
