In aquariums, snail leeches are a frequent but sometimes unwanted sight. These microscopic, worm-like organisms can cling to snails and cause discomfort or even damage to their hosts. These pests are common to aquarium enthusiasts, so it’s critical to know what they are and how to effectively manage them.
If these leeches are not controlled, they can harm your aquarium in addition to being an annoyance. They proliferate quickly, so as soon as you become aware of their presence, you must take action. Fortunately, you can control and even get rid of snail leeches from your tank if you have the correct information.
This post will explain what snail leeches are, explain how they procreate, and—most importantly—discuss the best ways to stop them from spreading throughout your aquarium.
Aspect | Description |
Appearance | Snail leeches are small, flat, and worm-like, often brown or dark in color. They have suckers on both ends for attachment. |
Habitat | They are typically found in freshwater aquariums, attaching themselves to snails or the aquarium glass. |
Reproduction | Leeches reproduce by laying eggs, which hatch into small, independent leeches. |
Impact | They can harm snails by feeding on their blood, weakening them over time. |
Control Methods | Manual removal, using a predator like loaches, or treating the aquarium with anti-leech chemicals can help control their population. |
A common pest in aquariums, the snail leech attaches itself to snails and other soft-bodied tank occupants, feeding on their bodily fluids and gradually weakening them. Because of how quickly this tiny parasite reproduces, it’s critical to detect and eradicate infestations as soon as possible. Hand removal, the introduction of natural predators, such as specific fish, and the cautious application of chemical treatments, which preserve other aquatic life, are all effective control measures. Maintaining the health and growth of your aquarium can be facilitated by knowing how to handle snail leeches.

Description
Snail leech (six-eyed clepsina, glossiphonia) is a representative of the family of flat leeches. Its size is quite miniature – 15 – 20 mm. Therefore, they are often not noticed, and are brought into the aquarium along with plants (bought in a store or brought from a nearby pond). The parasite has an elongated body, narrowed towards the tail, and a wide head, which gives it a teardrop shape. The color of the clepsina is usually brown or olive-brown with speckles, and it is able to attach to the body of the snail due to a sucker. A special proboscis allows it to suck a small snail out of its shell. And if the mollusk turns out to be larger, the leech will suck its blood. When snail leeches sense danger, they immediately curl up into balls. If you turn them over on their backs, you can see the eggs or small cubs that attach to the abdominal part of adult individuals. Leech offspring are usually carried on themselves. Until the cubs get stronger and are not able to lead an independent life, they feed on the prey of the adult clypsina, to which they are attached. The parasites reproduce sexually, while being hermaphrodites. Their lifespan usually does not exceed two years. Each adult glossiphonia is capable of reproducing offspring in the amount of one to several dozen similar creatures. Therefore, a snail leech in an aquarium can become a real problem. If you do not take measures to combat it immediately, the aquarium can become a breeding ground for these invertebrates.
The danger of leeches
The mouth apparatus of klepsins is equipped with a fleshy proboscis, which they use to suck the blood of small aquatic invertebrates with thin covers. The main target of these parasites is snails, which is why they received a second name – snail leeches. Most often, glossiphonia suffer from coils and pond snails. But mollusks that close the entrance to the shell with a lid are attacked by leeches much less often. If they get into an aquarium with tropical mollusks, klepsins are able to destroy them. And if they cannot find other victims, even fairly large ampullaria will suffer. Small fish have a particularly hard time: the leech practically bites into their body, after which it begins to eat the flesh through the wound.
Snail leeches pose a threat to humans as well because they can suck on them. If you see klepsins in an aquarium, you should not give up. Antiseptics are applied right away to the bite site because it can become infected.
How leeches get into an aquarium
Glossiphonia are typically added to aquariums along with live food, plants, soil, and mollusks that have not yet completed their quarantine. For a minimum of two weeks, any living thing should be housed in a quarantine aquarium or another separate container. Additionally, decorations and plants need to be cleaned. The best food to buy is live food that has been deep-frozen from reliable vendors. Snails kept in quarantine need to be properly observed. They might have a leech infection if they have stopped moving, spend a lot of time inside the shell, and dark patches have appeared on their bodies. After administering the necessary care, you will need to watch how they behave for a few more weeks.
How to deal with snail leeches
Regretfully, there is no definitive solution to the problem of how to remove aquarium leeches from aquariums. As of yet, there is no one right way to tackle this scourge. As such, those who are beginning it ought to exercise patience.
Most of the drugs used to combat snail leeches can harm the mollusks themselves. Mechanical removal of klepsin is the safest for the ecology of a home pond, but it is a rather labor-intensive process that requires attention. Snail leeches are individually removed from the aquarium with tweezers. But first you need to find them. Many parasites will sense danger and quickly hide in hard-to-reach places, including snail shells. To force glossiphonia to come out of the “house” of the mollusk, use salt baths. Snail for 10 minutes. placed in a container with a salt solution (1 h. l. salt for 400 ml of water). After this leeches usually leave their shelter. After this, the snail can be sent to a quarantine aquarium or to a common one, if you are sure that all its "passengers" have left the shell. Salt baths should be used no more than once a week, so as not to harm the snails. While they are in the quarantine tank, the main aquarium can be treated with chemicals. Such a measure will help to guarantee the destruction of the remaining parasites there.
Aquarium snails are at risk from any chemical method used to eradicate snail leeches. Therefore, some percentage of mollusks almost always die in the process of fighting off klepsins.
Chemical methods
- 1 measuring spoon per 50 liters of water on the first day,
- half a measuring spoon on the second day,
- and a quarter on the third.
It is not required to lower the medication dosage if there are a lot of leeches on the second and third days.
"Tetra Medica General Tonic" from Tetra is another medication that is used to treat snail leeches. One cap of the product is used for every forty liters of water. Shrimps should not be in the aquarium because they will perish otherwise.
Leeches trap
Using leeches in an aquarium to combat parasites is another non-chemical way to do so. A plastic bottle with multiple pre-made tiny holes can be used to make it. Inside the container is a piece of raw meat that will be used as bait. All you have to do is wait until the leeches are attached before wrapping it in gauze. After then, the meat with talled glossyphones is discarded after being removed from the aquarium.
Glass traps for planaries and snail leeches are already available for purchase.
Although they can be an annoyance in any aquarium, snail leeches can be successfully managed with the correct information. Maintaining the health of your tank requires an understanding of their life cycle and behavior.
It is always easier to prevent infestations than to deal with them once they start. These pests can be controlled with regular maintenance, close observation, and the introduction of natural predators like specific fish.
In the event that an infestation does arise, there are several ways to manage it, from chemical treatments to manual removal. Select the method that best fits your level of experience and the requirements of your aquarium.
You can make sure that your aquarium is a calm and healthy place for all of its occupants by being watchful and proactive.
