Bubble Coral - Polyp sagging?

[mm84]

Hi All,

I'm new to the forum (I've spent a lot of time reading!).

I bought a pearl bubble coral about 3 weeks ago, and seems to be quite happy, but I noticed today that a single polyp is hanging down. I'm not sure If I should be concerned? Otherwise, the bubble seems to be pretty happy and growing quickly.

My clowns have been attempting to host the bubble, so I'm not sure if perhaps they have irritated it? It doesn't retract when they swim around/above it, so it doesn't seem they are really bothering it.

I've tried to get a couple decent pics of the polyp hanging down. It's in a tough spot, and I didn't want to move it just to take a couple pics.

I should note that it's in a low flow/shaded area, and I've had some issues with cyano that is slowly clearing up, but it hasn't grown on the bubble at all.

Thoughts?

(sorry for the quality & size, I took these with my iphone)
