I don't think they are leeches. Looks like they have a hard outer shell.

Hi Everyone,

I have a question about some worms that I found. I recently built a
large pond and life is starting to take hold. I discovered millions of
crazy
worms and I was wondering if someone could help me ID them. There are
large
limestone rocks (fist size) directly outside of my outflow pipes.
Yesterday
I noticed that these rocks were completely black (we're talking 100+
rocks)
I had thought that it was black algae common seen in aquariums so I
picked
up a rock to check it out. The rock was moving! It was 100% covered in
these
1/4" worms. The water is moving fast. Like 100+ gallons a minute so it
cant
be mosquitoes. The rocks are completely submerged in water. Anyone have
any
ideas what these are? They have not been found anywhere else in the pond.

Thanks,

Sam



Could be leaches. I've run onto them lately, most are harmless/fish
food.
