Stylocoeniella Coral Care Guide

Stylocoeniella corals, most commonly known as “Thorn corals,” are small polyps stony (SPS) corals in the Astrocoeniidae family. Stylocoeniella corals grow by encrusting and come in a dazzling array of colors. Some of the most common shades are green, red, and orange.

Stylocoeniella corals require moderate lighting. We recommend 100-200 PAR.  Bear in mind that most corals can be gradually adapted to lighting conditions outside of their normal preferences. Thorn corals also prefer moderately strong water flow in which the flow path is alternating. 

Through their symbiotic relationship with a photosynthetic algae, known as zooxanthellae, they receive many of their nutrients.  Thorn corals may benefit from targeted feeding with rotifers and vitamins. To maintain good health, calcium, strontium, and other trace elements should be monitored and added as needed. 


When placing your Stylocoeniella coral, please remember that these corals aren't aggressive and have no real defense against other corals. Be sure to provide enough personal space for your Thorn corals to grow and thrive.
