I had the skeleton of the fox wedged in between to pcs. of rock for months until I sold it.
Here is some information:
The Nemenzophyllia Fox Coral is a large polyp stony (LPS) coral and is also commonly referred to as Jasmine Coral, or Ridge Coral. Its calcareous skeleton is very fragile and needs extra care when placing it between rocks in the reef aquarium. It is a peaceful coral that lacks visible tentacles during both day and night. Its polyps are white to pale green and are quite large, extending two to three times the width of its skeleton during the day.
The Nemenzophyllia Fox Coral is an easy coral to maintain, making itself a great candidate for the beginning through seasoned reef aquarist. It requires moderate lighting combined with low water movement within the aquarium. For continued good health, it will also require the addition of calcium, strontium, and other trace elements to the water. It will also benefit from additional food fed weekly in the form of micro-plankton or brine shrimp.
