What is THIS?

My blastos never really took off and I barely ever look at them. Over the past few days though I've noticed a bunch of polyps of a different kind overtaking the blasto skeleton.

They remind me of xenia but they don't pulse at all. They are almost perfectly maroon and match the skeleton so they are difficult to see.

Look like small Clavularia polyps, maybe a similar genus.

Anselth, I agree. I just googled clavularia and it really does resemble it. It does spread quickly too, just like the description said.
