Help Identify???

Not sure what this small what looks like plant or algae growing. It's started about 3 days ago after I added more live rock and fish so I'm assuming it came with them. It has double in size since then. It looks to be a reddish color. Just wondering what it will grow into? See pics. Sorry but it was tough to get a good pic.

I scooped it out with my net along with the sand around it just to be safe. Hope I don't see anymore.
