What Are Aquarium Leeches?
Knowing clearly about these parasitic bloodsuckers in your tank can help you find the exact treatment. Let’s get an overview of this species!
Aquarium leeches may come in various types. Here are the most common ones you may find in your tank:
Snail leeches are translucent, teardrop-shaped, brown, or white. They also look like caterpillars.
If your aquarium has many snails, it’s better to look out for this species and check your snails’ health.
The number of your aquarium snails will drastically fall if these clingers get into your fish tank.
For days, these parasites completely suck a snail’s blood. You should look for techniques to fight off these clingers if it occurs.
These organisms are dangerous parasites with brown tints that resemble earthworms. They mostly move throughout the Asian aquarium trade.
If your tank has shrimps, pay more attention to your pets, as these parasites can suck the blood of these creatures while you can’t notice.
These dangerous clingers, as their name suggests, suck on the fish’s blood and continue to do so until the prey is dead.
They are lengthy, warm-like parasites typically delivered to a tank by worms. However, this species rarely appears in the fish tank.

These bloodsuckers go through an entire life cycle.
Pond and aquarium bloodsuckers breed sexually, with the ovaries serving as the site of fertilization for the eggs.
Before delivering the cocoon, they create cocoons to which they attach the fertilized eggs.
When their eggs hatch, they release young bloodsuckers, and their cocoons are subsequently attached to plants or rocks.
These young clingers typically reach lengths of 15 – 30 mm and have a lifespan of around a year. The female clingers reproduce and then die.
These clingers are external parasites that may end the life cycle without a living host.
Overview of the parasite
Do Aquarium Leeches Kill Your Fish?
The short answer is yes! By suckling the blood of other living things, leeches – bloodsuckers, quickly multiply.
These parasites immediately attach to fish, sink their teeth into the fish’s epidermis, and begin sucking blood.
With their three jaws and razor-sharp teeth, clingers may readily bite into the skin, increasing the fish’s blood flow and preventing the affected region from healing.
It is challenging to detect little bloodsuckers since they are difficult to spot if attached to the fish.
By looking at the following signs, you may determine if your fish tank has these parasites:
- Fish moves slowly.
- The gills are yellowish and pale.
- The infected area is red.
- Fish rub against the tank surface to remove parasites.

How To Get Rid Of Aquarium Leeches
Once you’ve detected parasites in your aquarium, finding ways to kill them immediately is best.
Otherwise, these clingers will hurt your fish. Let’s consider these methods!
The first simple and safe method is using salt to kill aquarium parasites. You should apply salt in high concentrations.
However, these clingers may attach to the gravel. So, it’s best to prepare another container to dip fish, plants, or decorations rather than adding salt to the tank.
Additionally, salt doesn’t harm the helpful microorganisms in your aquarium. It’s advisable to apply pure sodium chlorides like Kosher salt.
Don’t use salt with additives or Iodized salt since these products may harm salt-sensitive and invertebrate species.

Potassium Permanganate Dip
Another risk-free method for eliminating aquarium clingers is potassium permanganate (KMnO4).
You can add this chemical to your tank at a dosage of 2 ppm. Your plants and fish wouldn’t suffer more.
You can soak your aquarium plants for up to 15 minutes in a 100 ppm KMnO4 solution to get quicker effects.
Potassium permanganate solution
You can remove some aquarium bloodsuckers with hydrogen peroxide. Sadly, some species survive after treatment.
It’s safe to apply H2O2 in your aquarium. Thus you can utilize this solution if you own any sensitive species or plant types.
If your tank has sensitive plants or fish, leech traps or Planaria traps are suitable as it comes with no chemicals.
Planaria traps have baits that contain clingers’ preferred meals, such as pork liver, shrimp, dead fish, and flesh.
Bloodsuckers will begin congregating within the baits to consume their preferred meal and become imperceptibly stuck inside.
If you are unsure how to make the traps, you can watch this video:
Copper is the most effective chemical for killing clingers in tanks with plants and fish. It doesn’t affect most aquatic creatures.
However, copper can be harmful if you keep invertebrates, shrimp, or snails in your aquarium.
Bleach may kill these clingers but not the eggs. Therefore, you might need to apply bleach numerous times over several days.
You must remove plants, decorations, and substrate and submerge them in water mixed with bleach to move bloodsuckers.
Before returning them to the aquarium, properly rinse them under clean water to dechlorinate them.
When bloodsuckers reside on the decorations, plants, or substrate, manually removing them is safe.
