So I just noticed all these guys in the over-flow of my 60g reef tank. What the heck are they? Good or bad guys? They are a bunch of them … about 1/8” to 1/4” in size … they have a tail, so they must be something (?). Also, see the tiny tiny curl … not sure what that is either. Forgive my naiveté … if something *lives* … I tend to think I’m doing something *correctly* for once!
