I have had the elegance coral in my tank for 2 days now, and I have to say what a beautiful coral. The coral look like its doing better in my tank than at the LFS. It has opened very nicely.
So far this is what I have done (via research) and its doing well.
1. Keep it on the soft substrate with the mouths positioned horizontally
and tenticals veritacally.
2. Do not expose the coral to intense lighting. If a lot of lighting then
build a cave to put it in or under an overhang (what ever it takes not
to expose it to intense lighting. I have Power compact lighting so it is
not too intense.
3. I am keeping it away from rocks in the middle of the tank with nothing
close to it.
One thing thing it does not like is to be a host for anenome seeking creatures. I am greatful my clowns did not take to it, but one of my anenome crabs is, so I have to keep chasing it away (unfortunately today the crab lost one of its claws
). Hopefully it will not bother it anymore or I will have to find a new home for it. For those that have the elegance coral this is what I have researched and implemented; so far so good. Hope this helps.
