Leeches

[Truck]

I have just taken out, what i believe to be a leech, its about an inch long and clear, and you can see its insides, ive killed it (please dont slate me) but i would like some info on them first.

If one bit me, would it infect me with a disease? two, are they beneficial to a tank/

cheers
