Stick experts please ID species

I got an acro because I thought the shape and growth looked super cool but I have no idea on the species. I have it acclimating right now. It has long very thin delicate looking branches with tiny little white polyps. Here are some pics of it acclimating

It seriously has the thinnest branches I've ever seen, looks so easy to break.

It kinda looks like a Acropora russelli which i have never seen in the hobby before.

Maybe Acropora subglabra that is growing thin?

Here is a pic of it in the tank. After looking at it I noticed the long branch is pretty beat up from shipping. Hopefully it survives.

Looks like an old school turaki to me but the branches seem way thin like a red dragon. No idea but cool pickup!

Turaki will grow in a cluster, and Red Dragon would be red and have lineage.

With the new pics i am leaning towards the russelli.
