Good or bad?

Everything I can think of to search for comes up with goofy results. I saw one of these on the front glass a few weeks ago, now there’s three on the back as well. Those are copepods for size reference.

Very likely some kind of snail egg.

Probably Snail eggs of some sort, also probably not the bad kind since they were put on the glass and not near/on a coral.
If you feel better if they are gone, just remove them

Ok. Thank you.
