The Tongue Coral is a large polyp stony (LPS) coral often referred to as the Tongue, Mole, or Hairy Tongue Coral. Its genus name, Polyphyllia, was derived from the Greek words polys (many) and phyllon (leaf), which describes the leafy shape of its calcareous skeleton.
Colonies of this species are often long and narrow, and arched or flat in profile, hence the common name "slipper" or "tongue." It is usually brown, but may also be cream or green and sometimes red.
The Slipper Coral is a solitary, aggressive coral with short tentacles tipped in white which can inflict serious damage to other corals in which it comes in contact. A preferable location would be on the bottom of the reef aquarium, lying on a fine sandy substrate, with adequate space between it and its neighbors.
It is easy to maintain in the reef aquarium, which makes it an excellent candidate for the beginning through expert reef aquarist. It will require bright lighting combined with moderate water movement, and 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
