Red, kinda leaf shaped... Algae?

[ChiefReefer]

Hello,

I have a 13 gallon tank that has been up for a few months. Overnight, I saw some of this red stuff turn up. It hasn't really done much since then. I tried to brush it off with the vacuum, but it's on there pretty good. Any idea what it is?

 

I looked through the various I.d sites and threads, but couldn't find it. Thanks for the help!

Hmm... I’m sorry I don’t know either... curious to hear what you find out.

Certainly an algae/seagrass.

Aqua cultured live rock?

 

Blue leg hermits would likely make quick work of it. I had a turf algae problem and bought some blue legs.. I previously had stayed away from hermits due to having previous ones pick at zoas. Withing a month they took care of the turf, as well as my dragons breath problem. No the dragon's breath wasn't really a problem, but they took care of it anyway. They kept snipping it off the rocks. Eventually they ate the hold fasts as well and well, now it is gone.

Thanks for the reply. It was live rock bought from an LFS that I suspect had been from a well established tank. Made for a quick cycle, but I think I would go dry rock next time to avoid some of the hitch hikers I've run into already.

You could also try Caribsea Liferock (next time)... quick cycle without the hitchhikers.
