Weird whitish "pouches" on my bubble's skeleton

[FishFrik]

There are like 5 or 6 of these pouches on my bubble's skeleton. They look like cotton balls with a small opening.

Here's the best picture i could get:

They are q-tip sponges. Harmless filter feeders.

Would they stress my bubble coral out?

Your bubble looks recessed already so maybe it would be a good idea to remove them. They should be pretty easy to remove by scraping them off.
