What could this be? (1 Viewer)

I'm assumeing it's some type of egg, but don't have a clue from what. I haven't added anything new for months & this is the first time I've seen these. In the pic, it's the white dots with yellow in the middle (center of pic). Please ignore the algae on the glass... 8O

It is hard to tell. Perhaps an air bubble surrounded by an algae film. But it could be an egg too.

It's definitely not an air bubble. There are about 50 of them & they are bright white with yellow in the middle.

flatworms? :? Try scraping one off and see if it moves on it's own.

I found out what they are, they are nerite snail eggs. I forgot I added some nerites a couple weeks ago.
