sounds like planaria. it won't hurt your fish, they just look bad. they will go away if you
1. cut down on feeding
2. do a couple good vacuums and water changes
3. add salt and turn up temp on tank
or you can use coppersafe i think it is called to get rid of them chemically
they feed on excess food in the tank, so if you don't have a pleco or other bottom feeder to help clean up after the o, you might consider getting one
