The fascinating story of aquarium snails is as delicious as algae! These multi-purpose misunderstood snails are more than their vibrant, yet unique exterior. They are popular amongst aquarists due to their beneficial and waste-cleaning instinctual nature.
The Benefits of Aquarium Snails:
Natural waste cleaners
Aquarium snails are known to be detritivores or “bottom feeders”, meaning they are scouring rocks, wood and plants for edible wastes that other creatures may have missed.
Having a waste cleaner helps to maintain cleanliness and reduces the growth of waste in your aquarium, which normally occurs over time.
Waste buildup can be detrimental because it can eventually lead to the pollution of harmful compounds like nitrates, nitrite, and ammonia in the water of the aquarium.
Algae Eaters
This benefit deserved its point. Algae, if not addressed, will grow uncontrolled and can even contaminate your aquarium water if in large enough quantities of specific variants. Most freshwater algae, however, aren’t harmful to fish in aquariums, but algal blooms are extremely unsightly. Good thing, these snails eat algae like it’s gourmet steak.

Natural plant fertilizers
What is captivating about this information is that this snail waste is the manure of the water, meaning their waste is a great fertilizer for aquarium plants. Their poop contains three main nutrients – nitrogen, phosphorus, and potassium that are needed for growing healthy plants!
They deserve their section in the Nat Geo Magazine
As mentioned previously, these vibrant colored uniquely engineered creatures hold a lasting impression on snail and non-snail enthusiasts. Their shells not only have intricate designs and textures but the shell shape and size add more novelty to their species.
To plant or not to plant?
Now that you have a good grasp on what aquarium snails are and the benefits of their eccentric existence, the next question is can they all be excellent planted pets? The answer is, it depends.
Sadly, but for good reason, some freshwater snails are considered pests by the majority of fishkeepers. So the real question should be, which aquarium snails provide less work in planted tanks?
Nerite Snails compatibility
These snails are well known to be the best algae eaters, making them great tank cleaners and filterers. However, the benefits list does not stop there. These species do not reproduce in freshwater which omits another concern of overpopulation. In essence, these snails require minimal upkeep.

Ramshorn snails compatibility
These snails are also known for their algae-eating ability, however, they can and will reproduce quickly; therefore more attention needs to be directed towards them if reproduction is one of your concerns.
Mystery Snail (Pomacea bridgesii) compatibility
These snails also make great tank habitat mates. They are generally safe with plants in the aquarium. The bigger their size the bigger the disclaimer. They also are considered algae eaters which is beneficial for maintaining the tank.

What do I do if I have a snail that reproduces a lot?
You simply get rid of them… partially joking
On a serious note, there are some steps to ensure your tank’s homeostasis is maintained without any fret.
- This one is obvious, manual removal. For some, you may have your work cut out for you, but at least you can rest assured that it is common practice to technically purge the excess snails.
You can use your hands to remove them, or you can opt for using a small net or tweezers to gently pick the snails off plants and tank surfaces. While you do that, it is a good idea to look for any snail eggs to mitigate more reproduction. The characteristics of these snail eggs are jelly-like clusters on glass/decorations. - Limiting the amount of feeding is necessary. Whether that be for your fish in the tank who may not eat all that you feed it, causing the snails to have more food at the bottom; or cleaning up the algae and detritus yourself to limit their food supply.
An influx of food is the primary reason for snail overpopulation. But why is this a phenomenon? Because just like any other living being on this planet, food creates a favorable living condition.
When coupled with the right temperature and enough moisture, it increases the snails’ likelihood of reproducing. Just to clarify, food does not directly cause reproduction for snails, but merely gives them the energy and nutrients to increase the chance to. In essence, giving your snail uncomfortable living conditions to reduce reproduction is the aim. Is this animal cruelty? That is for you to answer (Don’t hurt your snails). - Introducing predatory fish – This one seems a bit cruel. Some fish abide by the food chain and help to regulate the snail population. To name a few, pufferfish, clown loaches, and certain cichlids will actively scout and eat snails.
- Lastly, chemical treatments are another option. Just be mindful that cautionary measures are needed as this can harm other inhabitants in the same tank as the targeted snails. Copper-based medications are effective at killing snails but can have a lasting detrimental impact on the tank’s ecosystem.
Mystery Snail also known as Ivory snails (Pomacea bridgesii)
These strikingly fascinating snails resembling “golden apples” were briefly introduced, but let’s do a deep dive into these common freshwater snails. Besides being another snail algae eater and a detritus devourer, these snails are known for their ease of care and fascinating behavior. A fun trick they can do is climb to the top of the tank and parachute down, a phenomenon the snail community calls “para-snailing”.

Ramshorn Snail
As previously mentioned, these distinctively coiled-shelled bustling creatures will need more attention for population control as their favorite activity is snail breeding.
