Didn't buy these with my corals

[ReeferNoob77]

After about a month in qt I spotted these things slinking along on the bottom of my tank. They look a bit like a slug and have a thin shell on top. I might think they were snails except when I lifted the item they were hiding under they ran for cover. Only thing wrong with coral I have seen so far is the blastos I bought are all but dead.

I am working on getting a better camera but for now any possible ID? I did Bayer dip these before putting them in qt.

Look like limpets to me?

Stomatella.

+1 on stomatella from the current pics. Harmless but can populate a tank rapidly.

Stoma. IME , the stoma poulation will come and go depending on the availability of food. Just like pod and pod blooms.
Also similarly , predation is a factor.

Thank you for the quick replies. Glad to hear they are harmless.
