looks like either a maroon Valonia or some cyno covering standard Valonia.

Usually a member of the Valonia genus, this fast spreading algae can go from just a few "plants" to covering the tank in a short amount of time. Because of this you will want to treat it quickly, before the algae has the opportunity to send spores throughout your system.

Manual Removal: Like most algae, this species can spread from fragments. When you pluck them from the rock, try to remove it all from the rock and that may require scraping or it could grow back. Also try to catch any dislodged pieces. It is usually easiest if you get them small, cover them with a baster, scrape the baster along the rock, and when the Valonia comes off release the plunger and suck it up. Discard and repeat. Be aggressive with your manual removal, removing it every time you see it and you should win out.

Clean Up Crew: Mithrax crabs (Such as Emerald and Ruby Crabs) and Pitho Crabs will eat it, as well as certain Rabbitfish.
