What Are This Little Things?

There is about ten that grew in the tank. They are harmless but I am curious. Every now and then they release a thread into the water. Thanks all.

It looks like a vermetid snail.

Actually, they can irritate coral. Throw some bumblebee snails in there, problem solved .

Agree with the id and the solution. I recently popped a question up about some snails I had in my tank and kept running into these online. LOADS of advice and yt vids on them. I’d say get yourself a yellow wrasse. Mine eats all day and seems to get on great with everyone too. Plus, added bonus they are great to look at. But definitely keep an eye out for more. From what I read, if you’ve or one, there’s more and one is too many.
