Corydora eggs?

I went to do a water change this morning and found what I can only assume are eggs. They are small white balls and are sticking to the glass in various places in the tank. There are 37 of them. My best bet is that they are cory eggs since I only have a male betta and one snail that has been around long enough that I don't think they could've come from it. Plus 2 of my cories are hanging around the spots where the eggs are.

So on to my questions:

What do I do? I don't want any of the eggs to be hurt (eaten by the betta, knocked off the glass by the snail, etc... if these things are even possible). Should I move them to a different tank? Can I do so without hurting them?

I am fairly certain they were not there earlier when I fed the fish. How long should they take to hatch?

Any other tips or advice of info would be greatly appreciated. I have no idea what to do here. Thanks!

I would guess they are snail eggs; if so, this will not be the last time you see them. Were that the case, I personally would not do anything with them.

They sound like Cory eggs but I couldn't tell you for sure without seeing them. Cory eggs are placed in sets of 2 or 3 at a time all over the tank and they seem to favor placing them on the glass. The snail eggs that I have seen are placed in one or two cluster in a jelly like mass.

If they are Cory eggs and you wanted a cheap and easy setup to hatch them, go to your local pet store and buy a specimen container that hangs over the side of the tank. Aquarium Specimen Container Fill this with tank water and place it so it is submerged inside your tank hanging from the side of the tank. Carefully scrape the eggs off with a razor blade or fine pointed blade. I use a metal kitchen pie slice spatula and a very small firm metal strainer to catch the eggs if they dont remain stuck to the spatula. Place the eggs inside the specimen container and they will be kept the same temp as the tank and separated from the adult fish in the tank. I do this in my tanks so there is no need to have an extra tank; you just have to live with specimen container for a couple months.

This is the no frills setup and there are many things you can do to increase survivability. This would be a good setup if you are only interested in seeing a few of the eggs become young adults. I am sure the eggs are all gone but give it another month and you will likely see the eggs again.
