Black/purple dots on chalice coral?

[zmitty]

Hi everyone,

I recently noticed multiple small dark purple/black dots on the underside of my space invader chalice. The spots seem embedded within the tissue along the ridges/septa and do not obviously move.

I attached several pictures after putting it out of the tank. It is attached to a single stone.

Are these normal pigment structures for a Space Invader Chalice?
Or would you recommend dipping? If yes, what shoud I use?
Tank parameters are stable and other corals look fine.

Thanks a lot for any help!

Are they Vermitid?
Are they easily removed?
If the coral is otherwise healthy a intervention may not be warranted.

Thanks for your answer. They are actually not easily removable and seem rather integrated into the tissue. I also do not see any calcified tubes and have never noticed mucus webs so far, which made me wonder whether this may be something else rather than vermetids.

Any other ideas? Any Chalice experts/specialists around here? ;-)
