I found this on the back glass of my tank. It was gel like... does anyone know what this is? It’s small. Thanks!

Shouldn't have to worry about it being some kind of pest then??

the background is a napkin. I scraped it off. It's just that donut looking thing.

Those are eggs of some kind. Could have also been colonial tunicates I suppose. Hard to tell without seeing it's original look. Most likely snail eggs though.

Look like Nudibranch eggs.

I looked for pictures. The closest I got was zoanthid eating nudibrach. However, the pics show them on the actual zoanthids. This was on my glass. I’m gonna keep an eye out on my zoa’s. Hopefully all will be well. Is there something that I can add to the tank? Or would it be like a dip on each frag?
