Due to its similar appearance to a hammer and anchor shaped tentacles, it is named a Hammer coral or Anchor Coral Branching. Its polyps are visible in green, tan or brown color along with lime green or yellow tips on the ends of its tentacles that glow under actinic lighting and give it an amazing look. Sometimes, the Hammer Coral Branching is misidentified with the species called Torch Coral for having similar branched polyps. Its polyps are generally open and visible during the day, and at night it retracts and hides into its skeletal base. The Hammer Coral Branching mainly gets nutrition through photosynthesis which is done by the entrapped algae, Zooxanthellae, which is present in its tissues. It needs a supplement of calcium, strontium and other trace elements into the water for continued good wellness. The Hammer Coral Branching is moderately difficult to maintain, but if provided with proper water flow and lighting conditions it thrives well. It is aggressive in nature and features nematocysts or sweeper tentacles can extend up to six inches, stinging its neighboring corals, therefore it is recommended to keep the Hammer Coral Branching away from the existing corals in the reef tank. Due to its aggressive behavior, it is suggested to provide them their own niche, and if any damage caused by crabs, shrimps or other fishes, it should be immediately attended because it can cause a ?brown jelly? infection which can spreads to other corals. It is very easy and simple to propagate the Hammer Coral Branching that is why it makes a great choice for novice aquarists.
