I’m not sure if this is even algae. Just noticed it today. Doesn’t appear to be physically moving, the hairs are swaying in the wind though. All rock was caribsea life rock dry rock. Thanks in advance

Happy reefing!

Is there a mouth in the center of it or is it just my display?

No I don’t believe so. All I can really make out is the hairs

My wild guess based only on what I have in my tank would be a cluster of hydroids.
