Goniastrea is a genus of corals that belong to the Merulinidae family. Goniastrea are large polyp stony (LPS) Brain corals that are sometimes confused with Favia corals, but have a slightly different shape. The corallites of Goniastrea are arranged in deep valleys with walls that are a bit taller than the walls found on a Favia coral. Goniastrea are a hardy specimen of coral that can appear in a variety of colors and patterns.
Goniastrea corals require low to moderate lighting. We recommend around 100 PAR. Bear in mind that most corals can be gradually adapted to lighting conditions outside of their normal preferences. Goniastrea corals also need moderate water movement.
Through their symbiotic relationship with a photosynthetic algae, known as zooxanthellae, they receive many of their nutrients. Goniastrea corals benefit from targeted feeding of meaty foods like Mysis shrimp or brine shrimp. To maintain good health, calcium, strontium, and other trace elements should be monitored and added as needed.
When placing your Goniastrea coral, please remember that these corals are known to be a little aggressive. They have long sweeper tentacles that can extend to sting other corals that get too close. Be sure to provide enough personal space for your Goniastrea coral to grow and thrive.
