Mine's been doing great as well. Like N1z said, there are many new elegance coral farms popping up in indonesia and australia that are actually growing these corals out, fragging them, healing the frags, and then selling them. They appear much hardier than the disease ridden ones of the earlier part of this decade. I've been searching for info on the new specemins and some people on their way home from MACNA (wish I could have gone) offered me some info that was useful. I've been told that most of these new specemins were shallow-water collected species while those that struggled were deeper water species.
This makes sense to me because shallow and deep water corals have different zooxanthellae algae which are capable of using different wavelengths of light. Shallow water zooxanthellae can use many shorter wavelengths of light in the blue, green, and yellow spectra while deepwater zooxanthellae are only capable of using really purple wavelengths. It has been hypothesized (although not definitevely proven) that because these deeper water zooxanthellae are so specialized in the light that they can use, that their mortality rates were so high in captivity while the shallow water zoos were adaptable and survive in captivity. Therefore, the deeper water corals were bleaching, running out of photosynthetic energy, stressing out, lowering their immune system capacity, and opening the way to parasitic and bacterial infections to take hold and ultimately kill the coral. Their shallow water counterparts (popularly collected in the 90s, and again within the past year or so) had adataptable zooxanthellae algae which survived in captive lighting, thus allowing the coral to remain healthy.
That being said, when selecting a specemin at a shop you should still take caution to insure its healthy before you buy it. Things to look for:
Relatively long tentacles. Those with short stubby tentacles, are allready diseased and doomed to failure.
Non-swollen oral disks. Again, big oral disks, short tentacles, bad.
Good coloration. The coral should not be bleached or pale looking. Patterns in the oral disk should be prevalent and tentacles should be vibrant.
If in high-flow the tentacles should be fat and almoast bulbous (like a bulb tip nem)
If in low-medium flow the tentacles should be longer and thinner
Look for tissue recession at the skeletal break. These new elegance corals are often fragged at the farm in indonesia. Most come through the fragging process just fine, but some begin to recede away from the break-point. It's always very obvious where the coral was fragged (if its fragged). One or both edges of the colony will be dead straight, almoast as if cut with a chisel/saw
. So long as the skin is not receeding or peeling away from the coral there, its fine.
Also one word of caution when keeping them. Do your best to keep calcium, alkalinity, and magnesium levels appropriate. When I allowed mine to dip to exceedingly low levels just before switching tanks (<300ppm calc, <7dKH, and <1100ppm mg) my elegance started "bailing out" of its skeleton. Mercifully, returning chemistry to more appropriate seawater values ended the bailout and no polyps or mouths died, but the full recovery process will be slow I'm sure. Its slowly re-attaching to the skeleton. Anyways, just don't make the same mistake I did
And ritch, I'll leave you with first an example of my old diseased specemin which died (note all the examples of disease above), and my current 8 month old healthy specemin
