They were on my overflow box, as of right now there are no fish in tank, just cleaner shimp, snails etc. What are they, do I have to be worried??

Well, some could very well be flatworms. I can't see them but I am sure you are right. Most flatworms are benign and will disappear almost as fast as they come in a new tank. Again, nothing to worry about.

yeah I have the same flatworms in my tank and my clown eats them when they make their way up from th sump. Sorry I should have specified they are safe
