Cory fry

[Ellabee]

Hi. A few days ago I discovered my Cory cats laid eggs on the sides of the aquarium. I scraped them off with a razor blade and put them in a small tank. Today they are hatching, but there is some white slimy looking stuff in the water now. Is this from the egg sacks? Should I remove it, or is this what they supposedly eat? Just wondering because I read they first feed on the contents of the egg sacks.

Think that is kind of fungus.
Not the eggsac
