Eggs Whom?

So I came back from school and found this. My first time ezperience and i Don't kow who they belong to. They are everywhere in the tank including the walls. Now if they are eggs what should I do with it. The only fish I can think of are neon tetra and corydonas. I also have khuli loach. Let me know soon . thank everyone!
Posting from phone. There are a lot on the wall!!!

That sucks. What can I do to prevent the same from happening to me since I have assassin snails myself?

Do you have a spare tank? I think you can scrape the eggs off (gently!) and then move them to the spare tank. 

Of course. I have tanks. I will try to do that. Do I just throw them to the ground or do I need to build something for them to rest?
