Hitchhiker on my Astrea

[Ober_Reef]

Hello All,

Any idea here, been on my Astrea for a while now and does not come off easy. I do not have any algae issues in my tank. Just wanting to verify if it’s anything to worry about.
Thank you!

Any chance you can get a pic with less blues more whites?

Hopefully this one is better

I once glued green stars to a Mexican turbo snail. It was all fun and games for a while. Until it died in the back of my tank wedged against rocks I couldn’t get to. They started to grow everywhere.
