I was some type of limpet too, the second picture is of them all over a rockCan you get a pic of the other side? Looks like some type of mollusk, maybe a limpet or a baby snail?
O man, if that’s true I will have thousands of snails soon. They are everywhereSnail egg capsules
They do look similar but they are definitely moving, one day they aren’t on the glass and the next they are. They also move on the rocks.Look up nerite snail eggs
I have like 100 limpetts like this all over my tank. I dont have fish in my tank that ever ate them. Nor do I have a large cuc. So these guys reproduced and exploded in my ystem. They eat the algae off rocks glass, cyano, dinos....really they are quite amazing species of little snail. They can however get jammed into pumps because how small they are.They do look similar but they are definitely moving, one day they aren’t on the glass and the next they are.
