Tank Infestation

[roguekiller23231]

i've just looked in my small tank and horrified i've found these long brown worms, they are everywere, all over the tank, they are brown and about an inch or more long, and seem to be pulsating.

i've also discovered, and not sure how dangerious to the fish or me these are, they seem to be larve of some kind of fly/mosquito, they are very small about 4-5mm, and look like small tadpoles but have stripes along there tails. they are hatching, and i've seen very small white flys about.

now i havnt got a clue on what i should do?
