Just food for thought, but beware of jumping into an Elegance coral (Catalaphyllia jardinei) purchase. Their survivability rate in captivity over the last few years has been pretty dismal.
Years ago, I remember these being one of these easiest LPS
corals to keep. These days, they seem to be dying in huge numbers. There are a couple theories floating around now as to why this is. One subscribes to the thought that they are extremely susceptible to bacteria, and are infected before coming to the hobbyist.
Another theory is that many years ago (when these corals thrived in captivity), that our skimmers were of lesser quality, and our systems were quite nutrient-rich. Now, skimmers are keeping our water pristine-clear, and we are not feeding these corals enough, so they are wasting away.
I don't know which of these theories is correct (maybe a combination of both)?
These corals are found naturally on the muddy/silty substrate. They live in turbid, lagoon areas, and are solitary. They must be kept at a reasonable distance from other specimens in a tank; they are very susceptible to the chemicals from other corals, and can, themselves, send out nasty "sweeper" stinging tentacles.
They need moderate light, and very good water movement, though they should not be placed in direct current. Many times, when you see their tentacles shortening, and not extending, it is due to them being in too much direct current.
These corals need to be FED - at least week, especially if you have a protein skimmer. Chopped clams, scallop, squid, etc.
One more thought...these corals have fragile skeletons, and can be easily damaged during transport/shipment.
