most of the time when you see leeches they are the kind that just eat the gunk and muck...however all of them freak me out too...I got them in one of my pop up pools one year...I was in there misering around and got out and they were attached to me---I freaked out...after getting them all off I headed to walmart got some alum and dumped it in...It really worked--not sure how much is too much with fish...this pool didn't have any fish in it so I used the whole container...

It really did freak me out, I'll have to look into the alum and make sure it's safe for fish and plants. I'm sure you're way to young to remember the movie The African Queen, I've been laughing since I last posted because I had the same kind of reaction that Humphrey Bogart had to leeches...I kept feeling like something was on me and swatting and shivering! LOL

don't stress about it too much....they are probably just plant leaches. Plant leaches eat rotting plant material and are not blood suckers. They disgust me too though, no matter what they like to eat!!
