The Branching Green Coral, Euphyllia parancora, also known as the Anchor Coral, features hammer or anchor shaped tentacles similar to the Torch Coral's. It has brightly colored green tentacles, polyps often with neon yellow or green accents that especially shine under actinic lighting. The Branching Green Hammer is most active during the day and generally retreats into its skeleton at night. A photosynthetic energy-obtainer, it will also benefit from trace element supplements. It is best kept in a tank with moderate water flow and lighting and should not be kept near other corals due to its stinging nematocysts. If the Hammer Coral gets attacked by any organism, be sure to attend to it quickly as it can cause an infection for other corals.
