Slugs?

[Garfield]

Last week I bought some mushroom coral and turbo snails from my pet shop and everything had been fine until just now I noticed 3 slugs in my tank. I was worried one of my snails somehow became a slug but they seem fine. I havent seen the slugs until now so maybe they are nocturnal? Can someone help me identify them, do I need to get rid of them?
