ID this macro for me, please :)

Found this red/purple macro at the beach yesterday. Any ideas what it is??






And, is the one posted below Laurencia?

second one is laurencia I think

usually turn a more yellow color after being in the tank for a while..

I've got a handful of the top one too.. its still in my tank but about 75% of what I collected died the first two days so keep an eye on it

Thanks for the heads up. No idea what it is, though?

A type of gracc maybe?

Yeah, that's what I was thinking. There's so many types that it's certainly possible...
