The Yellow Polyp, Parazoanthus gracilis, features a bright yellow/gold body making it one of the few corals with this lustrous coloration. They are semi-aggressive but lack venomous tentacles. The Yellow Polyp feeds photosynthetically needing moderate lighting and moderate waterflow. They are susceptible to damage from Aiptasia-eating organisms like Peppermint Shrimp as they look similar. Each polyp is individual from the others and are easily propagated in the home aquarium.
I love yellow polyps, they're so much fun to grow. They are fast growing and love being spot fed like an anemone. One thing to note: they can produce poisons so care should be taken when handling, especially if you have cuts on your skin.
Really nice value, put them in and they all opened up right away. They're very resilient with my crabs climbing all over them. They close up and then reopen really quickly once the crab moves on. Very pleased with this addition to my tank.
