Galaxea Coral Care Guide

Galaxea are large polyp stony (LPS) corals in the Oculinidae family. Galaxea corals can be found in a variety of colors including tan, brown, green, pink, gray and purple. They are sometimes referred to as, “Crystals corals,” “Galaxy corals,” “Tooth corals,” “Starburst corals.”

Galaxea corals require moderate lighting.  We recommend around 100-150 PAR. Bear in mind that most corals can be gradually adapted to lighting conditions outside of their normal preferences. Galaxea corals also prefer moderate water flow.

Through their symbiotic relationship with a photosynthetic algae, known as zooxanthellae, they receive many of their nutrients. To maintain good health, calcium, strontium, and other trace elements should be monitored and added as needed. Galaxea corals may benefit from targeted feeding with meaty foods such as brine or Mysis shrimp.

When placing your Galaxea, please remember that these corals are aggressive and have sweeper tentacles that can damage neighboring corals. Be sure to provide enough personal space for your Galaxea corals to grow and thrive.
