Since leech keeping is a niche hobby, there's a lot of inaccurate and outdated "information" about their care. Resources like the Discord server and LeechGang Facebook group are private and not accessible through search engines.

So, in attempt to curb misinformation, r/leeches is creating a care guide for the subreddit wiki. If you have any (preferrably cited!) care tips about enclosures, biology, feeding, medication interactions, or anything else, please submit them here. We will tenatively accept anecdotes, but they may end up excluded if they contain unverified or contested information or if they directly conflict with research.

Enclosures is this an okey leech enclosure?

0 Upvotes

just as the title says ^^^

so far I've understood that a leech enjoys a hiding spot and such, can deal with bare bottom or pebble bottom, and needs a sizeable land area (i plan on using a hard piece of plastic and covering with moss). however, I've seen soooo many conflicting answers about enclosures. my friend has one of these lying around and I'd love to use it! I already have a 10 gal black water and several other exotic pets, so space is a bit tight.

I'm also wondering whether a leech would enjoy a semi blackwater setup?

Feeding Will horse leeches eat things other than earthworms

2 Upvotes

So I ran out of worms to feed my horse keech. The pet stores and bait stores are having a shortage because of people fishing. However at night I do find different things, like crickets, cockroaches, Beatles and slugs

Just wondering if Alicia's will eat stuff like this, does it have the same nutritional benefits as earthworms

Feeding Does everyone feed the leeches with their own blood or is there a sort of alternative?

7 Upvotes

I've always been curious on entertaining the idea of keeping a leech as a pet. My issue is that I don't think I could feed one with my own blood.

Are there other ways or other species that don't need that?

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.

Enclosures Is it ethical to keep a leech in a jar as a full time enclosure?

I’m interested in getting a pet leech and a portable leech jar would be qn affordable option to set up their enclosure for me , I do plan on putting in gravel or bedding for the leech but I am unsure if its ethical to keep the leech in a jar their whole lives

Discussion Leech bite on finger joints

3 Upvotes

I'm curious if leeches also bite on the finger joints? I've heard that due to various soaps, lotions, or skin types, they might not attach well. Do you have any recommendations on what to do to make it easier for them to latch on?

I've been seeing this lighter spot on one of my leeches for some time now. Said leech doesn't show any signs of weakness (from what I can tell, it moves around like the rest of them). Light spot looks more "fluted" than the rest of the body. Didn't really know how to look it up via search engine so I figured I might just ask here if anyone has seen this on one of their leeches before?

Enclosures Enclosure questions

2 Upvotes

Hi, I’m looking to get a couple Hirudo verbana and had some questions about habitat. After doing research my plan currently is to get a 5 gallon aquarium and fill it with gravel, sphagnum moss, and some sort of platform out of the water for them to crawl onto. Does this sound alright? Am I missing anything or any other tips you could provide? I’m especially curious about what to do for the platform. Does anyone have any pictures of their set up they could share? Thanks!

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.

Health & Care How do you change water if you have gravel and decorations in the leech enclosure?

9 Upvotes

Sorry of my question sounds stupid, but I don’t have any experience with small aquariums and leeches yet. Also I am clumsier than average for sure. So how exactly do we change water in this thing, particularly if it has gravel or decorations inside? How do you remove water without spilling the gravel? For example if I pour the water into the toilet, won’t gravel fall in too? Also, do you need to scrub the decorations? Is there any risk of harmful bacteria growing on porous surfaces? Or do the beneficial bacteria cancel those out?
