Anybody know what these are? I have hundreds all over my glass, they are about 1mm in size and quite fast movers when they do move.

Well, hello Mr. Flatworm! Hehe! Congrats...
 
These are not likely the "bad" ones. I'm pretty sure they're the harmless/beneficial ones. I would just let them be. The vast majority of flatworms are not problem critters... and even the "bad guys" aren't as bad as some people like to say they are. It's just that some flatworms have more a propensity to have population explosions that can just cover the tank. But again, I don't think these are the type... if you only have a few here and there, I'd say you might even be happy to have them. Some fish do enjoy snacking on them...
 
Ok thanks, will see how things go when I start to introduce some fish to the tank.
 
The flat worms tend to find their place in the ecosystem that is your tank, a population explosion followed by a stabilisation of sustainable life, you feed more they grow more etc, a 6 line wrasse or a few other FW eating fish are around to help.
 
Guys I Have Litteraly Thousands Of These Creatures In My Tank But There Darker With A Orange Centre Instead Of These With A Yellow One.id Say They Cover Nearly A Quarter Of My Live Rock And Cover Alot Of My Glass Have To Brush Them Off On A Daily Basis. What Other Fish Eat Them?
 
i think arrow crabs might do the trick
 
Congrats Viper - I too HAD many of these little flatworms. They are DEFINITELY reef safe... I too worried about them in the beginning. But never saw ANYTHING bad come from them..... Either they help as a cleanup crew - or as food! ;)

You should probably cut down on what you feed your fish, they only exand their population if there is spare food.
