Pectinia is a genus of corals that is similar to the group of corals known as the “Chalice corals.” Pectinia is also referred to as Spiny Cup coral. Pectinia are large polyp stony (LPS) corals. They have an encrusting base but grow forming little cups with spiny protrusions. A large colony is usually cabbage-like in appearance. For this reason, they are sometimes called “Cabbage corals.” Pectinia corals appear in a variety of colors and patterns.
Pectinia corals require low to moderate lighting. We recommend 100-125 PAR. Bear in mind that most corals can be gradually adapted to lighting conditions outside of their normal preferences. Pectinia corals also need moderate water movement.
Through their symbiotic relationship with a photosynthetic algae, known as zooxanthellae, they receive many of their nutrients. Pectinia 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 Pectinia 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 Pectinia coral to grow and thrive.
