Yes, Some People Are Keeping Blood-Sucking Leeches As Pets And It's Somewhat Terrifying

 

Do you know that keeping leeches as pets is actually a thing?

It is, if you ask me. But in light of humanity's disconnect with nature, and our concerning lack of knowledge about parasitic creatures, the idea that some of us are nurturing these parasites is also, uh, fascinating.

A leech keeper, Ariane Khomjani once said: “They're amazing, curious creatures that grow like crazy and make wonderful pets.”

Yes, he even explained how individual leeches have their own unique personalities, with some being more adventurous and others more shy.

In his words, “some like to try and sneak a feed more often than others, haha! But once they're full, they're content to sit and rest for a bit out of water if handled gently.”

Khomjani has four of these squishy vampires. The species he keeps is one of the larger types: buffalo leeches (Hirudinaria manillensis) from Asia.

What You Should Know About Leeches

Yes, Some People Are Keeping Blood-Sucking Leeches As Pets And It's Somewhat Terrifying

There are over 600 species of leeches worldwide and most, but not all of them, are blood suckers. Others, like worm leeches (Pharyngobdellida), are predators that swallow their invertebrate prey whole, while some species are detritivores that eat organic debris.

Leeches can have up to eight pairs of eye spots, which they use to detect the shadows of potential prey. Their brain bits are spread across 32 body segments, and they are hermaphrodites, so each individual leech has both male and female organs, although they still require a mate to breed.

If a hungry parasitic leech senses your body heat or the Carbon dioxide in your breath, it can loop its way towards you by using its mouth and butt suckers because their butts can also suck.

When a Leech finds a suitable host, it will inject its saliva - which contains anaesthetic and anti-blood clotting compounds - before biting down with two - or three-pronged serrated jaws.

Khomjani said: “Once they get feeding you don't even feel it, even with the large buffalo leeches. Although the initial bite can hurt a bit.” 

Leeches can go up to a year between feeds, but leech traders recommend feeding the larger species every 3-6 months.

Should You Feed Leeches With Your Own Blood?

No matter how tempting it seems, don't attempt to  feed a leech with your own blood without the consent of a doctor. This is because you may be allergic to leech saliva and can also be infected in the process of feeding them. Again, due to the anti-coagulants in the leech saliva, it can sometimes take several days for a bite to stop bleeding. This can be disastrous to people with a disorder in which blood doesn't clot normally.

Leeches And Human Culture

Leeches have been linked with human culture, particularly in Europe, for centuries. Leeches were primarily used for medical purposes, for around 3,000 years. During the Victorian era (in the 1800s) they were recommended for treating everything from headaches to nymphomania.

This craze led to a rather absurd battle between rival pharmacies, who produced increasingly elaborate leech jars in order to entice customers to choose their product.

This historic use of leeches severely reduced medicinal leech (Hirudo medicinalis) populations across Eurasia, so this species is now protected.

What Are The Usefulness Of Leeches?

Leeches are kept for use in both human and animal medicine around the world and are approved by the US Food and Drug Administration (FDA) as “medical devices”.

Leeches are used post-operatively in patients who have had digit reattachment or muscle or flap surgery.

The leeches are applied to the site and suck away the congested blood to allow for blood flow to the peripheries to keep the surgical site viable.

Some hospitals keep 100-200 leeches to make use of this blood-vessel clearing ability. These leeches are sourced from captive bred populations raised in controlled environments, to help minimise the potential risk of infection.

How You Can Feed Leeches Without Using Your Blood

If you want to keep leeches without offering yourself up as a meal, you can feed them raw liver or heated blood from the butcher. Provided the blood is fresh and not treated with any preservatives or anything like that.

If you want to keep leeches as pets, please make your safety and that of others around you a priority.

The Best Fish Feed in Nigeria for Catfish: Why Quality Matters

A few months ago, I visited a fish farm run by an ambitious aquapreneur who had high hopes for his homemade fish feed. His pond was large, his vision clear: this feed would cut costs, boost growth, and drive profitability.  But within a week, disaster struck. Fish floated belly-up. Growth stalled. The numbers didn’t add up.   The problem wasn’t the fish. It was the feed.   The catfish were growing exactly as they were fed: poorly. Just as fish can’t flourish on empty calories, a farm can’t succeed on subpar feed. The right nutrition makes the difference between a thriving business and a sinking investment.   In Nigeria’s competitive catfish farming industry, choosing the best feed isn’t just about cost, it’s about protein content, digestibility, floatability, and growth performance. The wrong feed leads to stunted growth, higher mortality, and lost profits. The right one maximizes yield, health, and market value.  In this article, we’ll explore:...

How Much Does It Really Cost to Start a Catfish Farm in Lagos, Abuja, and Port Harcourt in 2025?

After the Nigerian government hinted at a possible ban on fish importation , my inbox began to fill with a familiar question from would-be fish farmers in Lagos, Abuja, and Port Harcourt: “Can I start a catfish farm now and do it for less?” It’s a timely concern. With import restrictions looming and demand for locally raised fish climbing, 2025 could be a turning point for Nigeria’s aquaculture industry. But while the opportunity is real, the path to profitability depends on where you set up, how lean your operations are, and whether you can balance cost-cutting with quality production. A Market on the Edge of Change Nigeria needs an estimated 3.2 million metric tonnes of fish annually. Yet local production meets barely 30% of that demand. The rest comes from imports mainly mackerel, sardines, and tilapia; worth over ₦500 billion annually. A potential import ban would create an immediate supply gap, and catfish is perfectly positioned to fill it. Already a staple in Nigerian homes and...
