looks like planaria, caused from poor water conditions and too much feedings, not enough tank cleanings
 
They are in fact not planaria! They seem to be leeches....have you added any fish from other water sources?

Seriously compare that to the size of his fingernail, they're huge.

I'm not sure about leeches but they definitely don't look friendly. Only thing i can recommend is to try to remove as many as you can. Hope, your infestation doesn't last long.
 
they look similar to leeches which are parasitic. have you seen any of them on your fish?
