Is this acro some kind of tortuosa

[vpoiu1263]

I get this acro for 7 month.
But still dont know what is its species.
I put it on near high light place.
When I lower my light for 1 month.It get dark. Now brighten up light, it get back its original color now.

Hard to say definitively, but it could very well be a tortuosa.

Might be Austera

Looks like A. Austera to me. These are commonly called "Torts."

Thanks so much.

Gomezi

I have been wanting to add one of these to my tank for a while now. The local store has one but is charging way too much for frags so I will just wait till I find one in a friends tank or something. I love the light blue this coral gets when its happy and the cool growth thats looks like a mix of a few popular acros.

We would need to kill a small piece to have a better idea, and even then its not definitive due to varying morphology in an aquarium.

Here are skeleton pics of both tortuosa and austera.

The reason I was leaning "tort" was the more elongated taper of the axial corallites, whereas the austeras are usually less of an elongated taper. Also, the radial corallites are usually more "rounded" on an austera and more "spikey" on a true tort. I'm no scientist though.

Looks like a gomezi to me, defiantly more than a tort and defiantly more than an austera. But yea you would need a skeleton to have the best id possible.

Here's a pic from the net. Blue A. Austera. Looks really close to what you got.

Ausetera and torts can look so different from tank to tank. But the color of that coral looks just like all the gomezi I have seen and so does the tubular branches with more spaced out coralites. Its still just a small coral and once the branches grow out into a colony it will be more easy to tell an ID by looking.
