got this off my montipora - Good or Bad?

[5thgear]

I am researching as well any idea what this is? We have a montipora that had a Mont eating nudibranch and we seem to have gotten rid of it. the monty seems to not be getting worse now i found this today.

Asterina Starfish. Common hitchiker. Generally harmless but can skyrocket in population if left unchecked

+1 to the starfish. The green ones (yours appears to be green?) are typically algae eaters in my experience. I've heard the red ones can be Zoa eaters and the blue ones eat something else I believe...

makes sense the green eat algae, since it was on that monti i may pitch it just to be safe. I really appreciate the feedback i was researching before i posted and saw some dark ones can eat coral so i thought i would post.

Just keep an eye on them . Mine were well behaved for months untill they decided to eat my stratosphere zoas . Plus they multiply like crazy. Very good cuc tho .
