We just moved this guy to my husband's tank today which is why I was looking hard (I was at work and told him he could take a few he is having hair algae issues) and saw he'd taken the one with barnacles and this guy's shell if there were any babies the trigger and amount of hiding spots have kept me from seeing them
I have to agree that they look like snail eggs. My Nerites are prolific breeders but their babies usually only come out after lights out. That’s what their eggs look like though.
Probly why the triggers been sand sifting a lot more the last few days good to know the general of what I found and here is confirmed it's not parasites I noticed a bunch of tiny white dots at the top of my tank the other day and a couple big ones in my hob and figured they were laying eggs just didn't think it'd be on the shells of the others I never saw them on each other except when I first got them shipped in
Just realized I did see some babies in my husband's tank the other day this one may be one I gave him at the start just assumed they came in on the chaeto from the lfs
