ORA FrogspawnA classic entry level coral with intense purple and green coloration and hypnotic tentacle movement. This hobbyist favorite is tough and forvgfiving when it comes to environmental changes in the aquarium, but like other LPS corals, maintaining calcium, alkalinity and magnesium levels are crucial. Keep this species a good distance from other corals though, as it will extend long sweeper tenacles meant to sting its neighbors.
