Unlikely they will survive if you've fish in the tank.
Even if the eggs hatch, the tiny fry are seen as tasty morsels by most fish.
Adult corys will eat them too.
I used to remove the eggs to another small tank.
If you get the eggs early enough you can roll them off with your fingers.
They are very sticky and you can re-attach them to the glass in the small
hatching tank.
After a while though they harden and are not so sticky.
You can then get them off with a sharp razor blade.
If you move them use the same water - i.e. fill small tank with water from
main tank.
Use heater & airstone only - no gravel.
PS Only other fish I've had lay eggs on tank walls are Angels.
Cory eggs are bigger than angel eggs though.
If you get the eggs to hatch microworm is the best 1st food.
Ready Brek cerial and milk in a small pot seeded from a mature microworm
culture.

Thanks for that, I've managed to get some off the tank walls and I've put
them in a breeding trap for now.
There are prob, over a hundred left in the tank, some of the eggs have white
dots in the middle, are they the embryos? are is it fungus?
Some of the eggs I can't get to unless I take the tank appart, as some are
behind onr of the filterd and some on the temp stat.
The eggs are all clearish, and none look discoloured from a shell forming on
them, which I read is a sign of fungus.
They may be Otocinclus eggs, as I have a few of them in the tank as well,
but I'm thinking they are from the pair of Bronze Cory's I have.

Extreemly unlikely they are Otocinclus eggs.
Bronze cory eggs are perhaps just over 1mm in diameter and a light amber
colour.
Good eggs will stay amber and are translucent to clear.
Bad eggs will go white and opaque.
In the past I've raised broods of well over a 100 Cory. Aneaus from a single
spawning.
Later times when they spawned for me, I'd take the parents out and leave
only the eggs in the tank.
If well fed they spawn at about monthly intervals - usually just after
you've done a water change.
Try again if you have no luck this time.

Yeah I'd just done a water change about 2 days ago, and I noticed the eggs
yesterday, but I was in a rush, very busy as I work in retail at the moment.
I thought it was just a bit of dirt, or plant matter, lol, until I had a
look about an hour ago :)
They are all amber, and some have white specs in them. This is the first
spawning, They are amber, and about 1mm wide. am I right they take 5 day to
hatch?
My tank temp is 82F (28C) is that ok? or should I lower it?
The pair are still swimming about together, so looks like I may have a good
pair.
