The Purple Rim Plate Coral is interesting and easy to care for which makes it a very good choice for a novice aquarists. It requires only moderate lighting and little to no water movement. It is often referred to as a Disk Coral, or Chinaman Coral. The Purple Rim Plate Coral shows thick skeletal growth from between the ?flange? like growths and eventually move to the sand bed. It grows fast and needs a supplement of calcium and trace element in order to flourish. Supplemental feedings of meaty foods, Mysis shrimps can be given as target food to them for continued good health. Since the Purple Rim Plate Coral has short tentacles, it is considered semi aggressive and is capable of defending itself by stinging its neighbors. Its unique characteristics ensures its survival, i.e. its inherit ability to move itself to more favorable locations by way of inflating and deflating its tissues. The Purple Rim Plate Coral should be placed on a soft substrate, and it thrives well in a temperature range of 74-81 degree Fahrenheit. If placed on rockwork the underside of the corals polyp will be damaged by rubbing against the sharp edges of live rock causing stress and possibly death. An interesting fact regarding the Purple Rim Plate Coral is that it exhibits a unique behavior called polyp bailout that is to produce offspring in the event of death. This even happens three or four months after the coral dies and the offspring grows out of the skeleton and eventually move to the sand bed. Its propagation is quite easy and can be further fragged, or cut into half, to make two colonies. Though the Purple Rim Plate Coral is a photosynthetic in nature, it also benefits from a small piece of raw shrimp, frozen Mysis shrimp, or silverside once a week. After the lights are turned on the Purple Rim Plate Coral extends its feeding tentacles and quickly accepts food.
