Purple and Green Ancora (Euphyllia Ancora) WYSIWYG
Its skeleton grows in a continuous meandering fashion and is frequently referred to as the 'wall' hammer coral to differentiate it from the 'branching' hammer corals which have multiple heads that are separated by dead portions of the skeleton.
The coral is most easily distinguished from the similar Torch or Frogspawn corals by the shape of the tips of its polyps which have a characteristic anchor, hammer or T-shape to them which gives it it's common names.
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, stinging other species of corals and animals.
For continued good health, it will also require the addition of calcium, strontium, and other trace elements to the water. It will benefit from additional food fed weekly in the form of micro-plankton or brine shrimp.
