Eggs On Glass

Seapotatoe · Apr 7, 2022

I recently found these white eggs attached to the glass in my tank. Can anyone help me identify what they are from? I have corys in the tank, but I thought their eggs were more clustered? I also have two unknown snails (hitchhikers from when I introduced a new amazon sword three weeks ago), but they're tiny, less than 1/2 inch and the eggs seem too big to have come from them- I've attached a picture if anyone can help me ID those also. There's also guppies, a dwarf gourami, and a mystery snail in the tank.

Looks like snail eggs to me

I think they're cory eggs. They lay their eggs randomly.

It's not guppies (livebearers) or gouramis (lay eggs in a bubble nest). Mystery snails lay eggs in bunches above the water line. The pest snail in the photo lays a cluster of eggs in jelly. That leaves just the cories.

Thanks! Is it okay to just leave them? Is there any way to tell if they're fertile? The gourami is already trying to eat them so I doubt they'll survive...

Also, Do you know what type of pest snail they are by any chance/ if I should remove them from the tank?

Eggs usually get eaten, unfortunately. If you had another tank just for raising cories, you could carefully remove the eggs and transfer them but in a community tank they are just seen as food.
Infertile eggs are usually opaque white, as are eggs which become fungused.

The snail looks like the type with several names - pond, trapdoor, bladder etc - one of the Physid snails.

Cory eggs, definitely. Mine was eating the first ones it laid as she was laying more right next to them. As already been suggested , taking them out to a breeder tank/box would be the way to save them, assuming they're fertile, which has also been explained (as to how to ID them)

This is my set up right now lol. I scraped them off the class, and stuck them in here. I'm planning on running out tonight to grab a small tank to grow them out in, if they hatch. Thank you everyone for the advice!

That's what I thought too.

Just out of interest, here's one of my angels laying eggs yesterday. She ate them all within half an hour as her partner angel didn't seem to want to fertilize. I have a feeling they're both female.

The white spot on the right is a Nerite egg.
