Anemone on GSP??

[saltyMJ]

Just noticed this guy on our GSP coral. We don't have any anemones in our tank, other than a few aptasia. But this guy looks different? Any ideas?

Looks like gsp

Honestly it could be a lot of things, and it's hard to tell because it looks upset right now. Best guess is majano or aiptasia based on the shape and size.

It’s really hard to see in the pic, but I think I see distinct spheres on the tips of the tents? If so, my guess would be a ball anemone (Pseudocorynactis caribbeorum), which is actually a mushroom and generally harmless.
