Can somebody please tell me what is growing on my back wall. Tank is over 2 years old and it literally popped up over night. Never seen anything like this. Thanks in advance.

Snail eggs? Or something eggs would be my guess lol

Hopefully I'm thinking the same, but I really don't have a clue, lol

Pics aren't super clear, but snail eggs would be my guess there too.

Looks like snail eggs, cerith snail eggs are circular on glass so im not sure what snails you have in your aquarium. ( trochus snails release theirs into the water column and wouldn’t be on glass)
