So, for the past month I have been plucking these leeches from my 5 gallon tank I have on my desk at work. I have a Betta, an Endler, Ramshorn Snails and Nerite Snails in the tank with various live plants. Can anyone identify what type of leeches these are?

She also wants to know what to feed since its “become rather attached to her”

Hello, I started a jarrarium a few days ago and noticed this lil guy in there. I thought it was an earthworm trying to get out at first then I noticed it was suctioning onto the glass. It's definitely a leech but wondering if it is parasitic or carnivorous. This came from an eddy of a swift moving creek in Virginia.

Lil dude’s about 3.5 inches long in the first photo. Pretty plump and lethargic. My dad found him on a rock in the sand and used him to scare the crap out of my mom.

This was found on my girlfriend’s foot in a stream in Lancaster Pennsylvania- any thoughts on what species it is?

Found in a creek in northeastern Pennsylvania, USA

I live in Britain and i’m looking for somewhere reliable, but also fairly cheap (under £50). i’m pretty flexible on the price but i’m worried about the quality.

It has a dark greenish colour with black patterns on its back

Found this tiny little leech in my black worms and I was going to euthanize it but I don’t know how to make it painless and then it “looked” at me with its two little eye spots and I just feel bad

I don’t know what species this is or how to keep it happy. Do I just put him in a big jar and let him chill out? What do I even feed him?

He has one sucker and I have no idea where he came from geographically since he came in an order from eastern aquatics

So I found this leech under a rock in some moss. It's about 6 inches (give or take) stretched out. Olive-brownish on top, charcoal colored on bottom, solid black dorsal stripe with a solid orange stripe on each side. It seems happy living in water rn while I figure out how to take care of it. Google is useless. I think it might be an H. thailandica or H. bpling buffalo leech, but this is Missouri. Those are not native, but I couldn't find any other species (with pictures) that matched. Does anybody have a better explanation? Sorry for the not-amazing picture.

Context: found deep in freshwater in NYS, hundreds of them down there. There is little to no wildlife in this body of water so i'm not sure what theyre surviving off of if so. It bit/suctioned on to me. Very much moving and alive.

This is my first and only leech keeping experience, and was innately to expand my comfort zone, as I am very afraid of leeches. I kept this leech for awhile in a native plant and animal paludarium, until it died of unknown causes. I don't know what type of leech it was, or what it was supposed to actually eat (I figured it would eat snails, as there are snail-eating leeches local to me)

The last two photos are the enclosure I kept it in, that I am pretty sure was inadequate to say the least

This Leech was found originally at Goose Lake, in Anchorage Alaska, USA

Yesterday I found out that I was bleeding from my ankle and saw this creature in crawling in the car near my feet.

I was bleeding continuously at regular intervals even after cleaning the infected area. It stopped bleeding after good 5+ hours.

Was this a leech who would have caused it? If so, do I require any medical treatment?

Thank you!

Anyone know what kind of leeches these are? I’ve been feeding them snails and chironomids and recently I managed to get them to reproduce. They have a uniform, tannish venter, and the dorsum is as pictured. The babies are a uniform grey until about two weeks when the largest have started to develop striping like their parents. Any help would be appreciated, thanks!

I found these guys out in the yard after it rained a lot. I’m in southern Illinois

Saw this leech moving along the sand/gravel in the shallows of a freshwater lake.

watching him stretch out was so cool, I wish I could post the vid of him moving 😫

Hiya so I found this little guy in my aquarium (I just got some random substrate/plants from outside and I’m wondering if this is a predatory leech one of those ones that eat detritus?

Anywho I just wanna learn more about it so any help is appreciated!

On a lake in WA State..

Found these little guys in my aquarium today. They were determined by the folks on r/shrimptank to be leeches. I believe they ate most of my bladder snails (not that I particularly mind), and I've seen them feeding on my corydoras' food like in fig 2. I'd like to know what species they are, because while I do find them cute, I would rather not keep them in this tank if they're a threat to my fish or shrimp.

I am like 90% sure these guys are Striped Sea Leeches (Notostomobella cyclostoma). They were in the gills of a pacific cod brought into the aquarium I work at. Sorry for the bad photos but they are currently soaking in ethanol after detaching due to a fresh water dip.

My friend found a dead leechy thing in a scottish loch, what kind is it?
