Don’t see it…

 

[munjy]

Sorry about the lack of detail, hope this helps. They are in the channels of the coraline.

 

[munjy]

Maybe tunicate?? Good or Bad????

 

[chrisnif]

I'd say sponge or truncate and probably wouldn't worry, but let one of the big dogs answer so you can be sure

Colonial hydroids
Not good anyway you slice it. Opinions vary on their nastiness, but definitely eradicate immediate.

 

[munjy]

What would be the best way to eradicate? There are bunches of them. Thanks very much for the ID, much appreciated.

They look like Colonial Tunicates to me. But, there may be a hint of tentacles that I can barely make out. If they have tentacles then I believe AquaKnight is correct.
Can you send a full size picture to my email?

They look like eggs of some sort to me. I have colonial hydroids, I just scrape them off and syphon what I can out when I do water changes, but mine look NOTHING like that. Maybe I have the wrong id?
