Got a picture of them? They could be midge (mosquito larve), something that came in on aquatic plants, if you have them or even from live fish if you feed them to your turtles. If they were white, they could be planaria (harmless) from debris in the tank (which those rocks will trap).
I'd clean well, rinse with hot water and see if they come back.
