Don't panic Bette! ;-)
Most leeches aren't the blood sucking variety.
They eat detritus, slimey bits of this and that.
I've kept them in with an aquatic frog to clean his gravel. Named the leech
Osama bin Leech.

You can test your leech with some raw liver. If he goes of it then you can use
the trick BV mentioned. If they are in the main pond you can put the liver in a
clamshelled strawberry basket to keep the fish from eating the bait.
