Unknown white blob on fish tank

[Valerie Joe]

I found this on the wall of my fish tank. I thought they might be frog eggs or something but I don’t know..
If anyone does know, please do let me know..

Is it a spider egg? (Cocoon?)

Any chance you can remove the mesh and get some photographs of whatever it is?
