You have some eggs that will hatch into baby Cories. I am glad you removed them, as the adults will eat them pretty fast. Now I hope they are in a separate container than the baby guppies, size is amazingly different between them, and babies can eat them, too. The hatched eggs will be almost microscopic, you will need a magnifying glass to see them and know it is not just junk on the bottom of container.
Clean up any unhatched eggs, as that will add problems of bacteria and fungus to the water. Use something small like a Q-tip and not like the normal cleaning apparatus, as the babies are way too small for using that. Also, put a stone/bubbler in the vicinity of the eggs to keep fungus off of them. They will hatch in appx. 7 days.
After hatching, they will need some live plants to help them get started, and if you have any Hikari First Bites, that is good food for them. Plants have infusoria which hatchlings can eat. You can also buy that in a fish store. You can get some Baby Brine shrimp, but whatever they are fed has to be broken down into tiny bits so they can eat it. I have some hatchlings now, and use the Hikari and plants. I have the shrimp pellets, but can't tell if they are eating it -- it has to break down for them to nibble at it. They can also eat the algae, and you can put in an algae pellet that will break down later, so try to grow some algae yourself.
Good luck, and you will need a private place for them to grow after they are big enough to see and you can watch them -- at first they are nothing but minute stringy blobs!
