gold fish eggs everywhere

they wont be fertilized because she is the only fish there.

So, if you want you can just leave them there.... they will get yucky, grow fungus.. but they will break up on their own.

Or. what ever the eggs are attached to ( rocks, decoration etc..)
take it out and let it dry.
Then brush them off and put it back in the tank

It wont hurt her, or you, but leaving them there if you dont want to touch them is fine as well . It will just be yucky to look at.
