Hard bubbles on my conch? Is it bubble algae or eggs?

Both conches have them and I tried to brush it off in a separate container but it wouldn’t budge. That’s what made me think their eggs but since I’ve never dealt with bubble algae only heard of it I’m not sure

Looks like bubble algae. I would remove him from the tank to remove the bubble and place him back in.

Be sure to rinse off the shell before putting it back in the tank. The liquid in the bubbles contain algae spores
