Definitely algae of some sort, aiptasia is more brown in colour.

I see 1 piece of bubble algae and a few pieces of algae. Depending on what is in the tank algae eating wise it may clear it. On the other hand if the snail is in an area that you can reach gently pick it up and remove it by hand. Shouldn't be that much trouble.

Have a great day.
