GSP dead?

[alyrchd]

My GSP got covered in hair algae but was still opening just fine. One day i decided to brush it off and ended up hurting it a bit. It began to open less until this point where i believe it’s dead. Is there a way to revive it or is it long gone?

I don't see any GSP on that plug. It should be a thin purple mat that the polyps come out of.
If you really want some GSP, check with local reefers. They're usually giving it away since it's such a fast grower and many times invasive.
