Australian Toxic Hammer
The Hammer Coral is a large polyp stony (LPS) coral and often referred to as Euphyllia Hammer Coral or Anchor Coral. Its common names are derived from the appearance of its hammer -like, anchor-shaped tentacles. Its polyps are visible throughout the day and night and hide its skeletal base. It may be gold, green, tan, or brown in color, with lime green, yellow or pink tips on the ends of its tentacles that glow under actinic lighting. Some varieties may be branched which makes them look similar to a Torch Coral (E. glabrescens).
It is moderately difficult to maintain, but with proper water conditions in the aquarium, it will thrive. It will require moderate lighting combined with moderate water movement within the aquarium. At night, its sweeper tentacles can extend up to six inches in the reef aquarium, allow plenty of room between it and other neighboring corals. For continued good health, it will also require the addition of calcium, magnesium, strontium, Iodine and other trace elements to the water. The LiveAquaria Hammer Coral will benefit from additional food fed weekly in the form of micro-plankton or brine shrimp.
