Are THESE Cory Eggs? *Updated*

My peppered Corydoras have been getting frisky recently (or at least I think that's what they have been doing!)... Tonight I spotted this (these?) within some of my pond weed... Are these Cory eggs? Or something else?

If I am likely to end up with Cory babies I want to give them the best start!

snail eggs I think, but not cory

Ahh. Shame... I only have one snail in my tank, arrived as a happy accident with a plant purchase! I believe "Snail Dude", as he is lovingly known in my house, is a "bladder pond snail" - does anyone know if this type reproduce asexually? Thus are the eggs likely to become mini "snail dudes"?

Yep thats a bladder snail egg mass. They will reproduce on their own lol

Well thanks for all your helpful info... The egg mass has now disappeared so i figure they have either hatched and been eaten, or just been eaten... or possibly just so small that I can't see the baby bladder snails?

Just noticed these though... Are THESE Cory eggs? And if so what's the chances they are fertilised, and if so, what's my best plan for fry survival?

Sorry for poor photo quality, my wife sent me the pics and her camera doesn't like to readily focus on the glass or eggs!

Yes those are cory eggs.

You can gently roll them off the glass using your finger and place them in a container of water taken from the parents tank. Use an airstone. Add a few drops of methylene blue or an alder cone to prevent fungus.

After 24 hours if they turn white they are infertile and should be removed. Fertile ones will usually darken. Check several times a day for fungused eggs and remove those.

After 3-5 days they should hatch. Don't feed for 3 days after. After that, offer fry foods (theres an egg yolk option on here somewhere if you search, Hikari First Bites, Baby Brine shrimp, microworms, etc) several times a day. Make sure after they hatch you do total water changes on the container, using fresh water from the parent tank.

After 7 days, add sand to their container, even just a small layer. The beneficial bacteria in the sand helps them thrive and protects their barbels.
