Convict fry went from wigglers to free swimming, and I noticed a bunch of spots on my tank walls... egg shells? Couldn't get a good angle for a pic and not super concentrated. Came off with very little effort.
Can you expand anymore on the 'spots'? Are you sure it wasn't fry feeding on some of the algae there?
You're right, it does seem like eggs. Although if they're translucent that would indicate that they're fertile. Then again, if there's not a high concentration of them you'd think they wouldn't be eggs. I've had a similar situation where lots of my eggs disappeared, but looking closely you could still see a few transparent eggs in the same exact spot. I personally wouldn't take much notice of them if the parents aren't guarding and they seem to be spread out. Maybe someone else will know more?Positive, these are semi translucent. Oval shaped and not moving on their own.
