I'm pretty sure it's a Christmas Tree coral, as it exibits the typical "shrivelling up" behavior occasionally, which my colt coral does not do.

I suspect that with the colt, sinularia and Studeriotes sp being so similar in many ways, that a positive ID would be difficult unless done by an expert, which I am certainly not.

In any event it looks similar to pictures I've seen online, behaves similarly to published texts, so I figure it must be a Christmas Tree coral? :?:

But it's good to hear that it's settled in.
