are these eggs??

I have about 50 of these on the glass. They don't seem to do much, but I'm at a loss for what they are.

 

They kinda look like baby sand dollars.

 

Nerite eggs, I believe.

 

I do have nerites in the tank... hopefully it'll help keep the tank clean. How long until they're not stuck to the glass?

 

They usually just dissolve in a couple days, or something else eats them.

 

hmmm, these have been there a little while. I'll keep an eye on them.

 

I have them too. They kinda just dissolve but noting comes from them that I have noticed.

 

Nerite eggs and unfortunately they do not survive in our tank. They need tide pool environments to hatch.

 

Yes, these are looking just baby sand dollars.
