so only last night I noticed that my corys had layed eggs on the back of my thermometer in the tank, and when I looked it up it said they will have a black dot in the middle when they are about to hatch, as I have had eggs before but my gourami ate them all, and now that he is in quarintine for fin nipping the eggs have survived and all but a few dont have the black dots in the centre, as I dont have another tank to raise them cause my 20l tank is being used to treat some sick neons, will the 4 adult corys eat there babys once they are hatched? as I have no where to put them our anything to feed them unless they will eat cyclops which is what I feed my corys often. any advice would be helpful.
30-40 Cory Eggs About To Hatch

You can make a small breeder box out of plastic box or I've even seen a coca-cola bottle but I won't recommend that if you've nowhere to house them after a couple of weeks. Corys grow superfast. At 4 weeks old mine were 2.5-3 cm long and chunky. 30-40 babies months would require a large enough tank for themselves pretty soon. As feeding goes, flake food made as super fine powder, dropped at the bottom will do for a good while. Cyclops could be too big for them as cory babies are very very small when born.
If you don't have the time, the available food and the space to raise them, just leave them be where they are and hope for the best.
Not many if any will survive the lack of edible food in the main tank and the adults chasing them as food when too small. As for the dots in the eggs, I haven't been able to see dots in all of mine but some were albinos.

If you do keep them in a plastic box, make many holes on the sides that are small enough for very small fry not to escape, then cover the bottom with sand and put as much moss/moss ball/plants as you can spare from the main tank. To feed them you can also use the mulm/sponge squeezing from a mature filter. It will be perfect food for the first week. Don't worry about not being able to see them inside the mulm. But do make sure you flush the water inside the breeder box several times daily otherwise you'll suffocate the little corys and also ammonia can build up. The holes never provide enough circulation. Then after a week feed them powdered food 4-5 times a day and remove the clamped left overs ones a day.
After that, you can buy a big plastic container from the hardware store, put a spare and cycled!! filter inside with a heater(or if room temp is 22-26 degrees it will do) and just decorate it as a tank. Fish won't make a difference.

I have a breeder box but my nasty gourami is in there until it can be rehomed as its just recently started attacking them all the time, so I will just have to leave them and even if 1 survives I will be happy, and next time the breeder box will be available once the gourami is gone. I was reading on a cory breeding post that at the 3-4 day mark they you will start to see a black dot in the middle when they are close to hatching and that they will eat there egg sac for the first few days as mine are bronze corys. so will just hope for the best as if more that 2 survive the rest will have to be rehomed as the tank in only 60l, and thanks for the quick informative response.
