Rock Flower Anemone has a cyst.

[JakartaOrBust]

So I just noticed this brown cyst looking lump on my rock flower. It's just under the lip of it before the base. I would show a pic but I cant find my camera at the moment. Its in perfect health though and doesnt seem affected by it. But is it something to do with asexual reproduction? Has anyone experienced anything like this? Ill try to find my camera.
