Plate Coral

This coral receives much of its energy by utilizing the photosynthetic algae contained within its tissues. It also requires occasional feeding; it is able to consume foods such as mysis, enriched brine shrimp and pellets. It is often the favorite host of small commensal shrimp such as Periclimenes sp.

When handling this coral it should be picked up from underneath, and allowed to fully retract before removing from the water. It is prone to physical injury, especially if removed from water while inflated or from falls due to incorrect placement. It is less able to heal from these physical injuries than most other corals. It is however known to be virtually pest free.

This interesting coral is free-living on the substrate, preferably sand or rubble. It has the ability to “walk” across the bottom and even over small rocks. It has some ability to rid itself of sand, however it takes a great deal of energy. Plate and Tongue corals of all kinds can live together as they do not sting each other. However, they may damage other corals by depositing thick mucus onto them.

An often perfectly circular coral with short, wavy tentacles and a single mouth in the center, it makes a perfect addition to the lower areas of a reef. A variety of colors are possible, typically green or purple, sometimes with highlights of a contrasting color.

Water flow is best provided as turbulent flow with the use of a wave maker or surge action. Constant laminar flow is very damaging and could cause death of the coral. Alkalinity, calcium, magnesium and strontium are required for growth and should be checked regularly.
