In this picture, if you look closely, you can see three generations of Golden Ramshorn Snails.

Ramshorn Snails

Rams-horn snails are a wonderful addition to any freshwater aquarium. Their shell is a beautiful natural, ancient shape and they come in a variety of colors and sizes. I have seen snails with shells of blue, red, brown, golden, yellow, pink, as well as mixed colors. Some ramshorn snails also have a spotted or lepoard prints on their shells. They eat algae and left over fish food that can make the water dangerous for fish. Snails are great at revealing water quality too. If you see your snails remaining at the surface at the water line and actually trying to climb out of the water then you know the water is not safe for your fish and it is time for a change. 

There is a lot of negativity towards aquatic snails in the aquarium because they can over populate easily. Overpopulation usually occurs when there is an over abundance of food, and or there are no natural predators of the snails in the tank. The fact is that most fish will eat the baby snails and the snail eggs if you let them. Even the grown snails will eat their own babies! If over population of snails is ever a problem there is no need for poisons to eradicate them. All one needs to do is put a clown loach in the tank with the snails, which is a type of fish sold at almost any pet store, and it will eat all the snails that are smaller than itself. Clown loaches are passionate when it comes to snails.

Another myth about snails is that they eat all your aquarium plants. This is simply not true. Some smaller snails do eat aquarium plants but not to the point that the plant is destroyed. Rams-horn snails do not eat live plants but dead plants or plant decay. This is very beneficial for keeping your water quality in your fish tank at its optimum levels.

Do Ramshorn Snails Carry Parasites?

Ramshorn snails have been known to carry a parasite through its life process and eventually end up usually infecting and killing fish. This happens in the wild because the parasite is given the chance to complete it's life process which takes about 30 days. Most aquarium snails you buy have come from aquariums and have been isolated over 30 days so the parasite has not completed its life cycle there fore eradicated. You should always be careful of disposing of aquarium water. Never throw it in storm drains or rivers or lakes. That can lead to introducing foreign plant and wildlife into the natural Eco-system which can cause a lot of problems, even lead to the extinction of native species. As always, be clean about things and wash your hands before you work with your fish, or snail tank, and after.

All in all aquarium snails, especially Rams-horn snails for their beauty, are fun safe pets that enhance the aquarium experience. They add a necessary element to your personally created Eco-system.


This is a Clown Loach, who loves snails. So be careful, or be thankful.

Ramshorn Snail Facts

Ramshorn snails breath through lungs and have to go up to the surface for air. They also can carry a bubble of air inside their shell which they can use like a ballast to pop up to the surface of the water or sink down to the bottom of the tank when needed. Ramshorn snails can live about two years or longer with luck. Most types of these snails grow to be about the size of a quarter or larger. Ramshorn snails can live in slightly brackish water which make them good tank mates with guppies. Fish that are on the aggressive side usually harass snails endlessly. Sometimes they are even harassed to death by starvation because they won't come out of their shell to eat.

Even though these snails are fun pets some find it beneficial to keep Ramshorn's and breed them to supplement the diet of their other aquatic pets. As already mentioned before, clown loaches eat snails, but many other fish like them. Other known snail eating fish are catfish, puffer fish, goldfish, betta fish, and barbs.


Snail Eggs

Life Cycle of the Ramshorn Snail

The first snail of this clutch of eggs, in the picture to the right, is ready and will leave the others to make its first trip the the surface for air. The ramshorn snails eggs are laid sometimes as duds as you can see in the picture to the right. The egg cluster will simply look empty or jumbled up. Unfortunately, sometimes things just are not meant to be.

Ramshorn snails are hermaphrodites, which means they carry both male and female sex cells in which to create offspring. They do however, need another snail to exchange these cells with to mate efficiently and successfully.

Since ramshorn snails carry both sex cells and organs they decide when they mate who is depositing sperm and who is receiving it. They change back and forth between female and male when mating. They are also capable of auto-fertilization because they do have both sex cells withing their bodies. These baby snails will be exact replicas of the parent, or clones of the parent snail. If these snails breed with each other the gene pool will become exhausted and genetic defects will start to arise, with offspring that do not thrive or sometimes even make it at all. Usually, in the wild if this auto-fertilization were to happen, other snails with new genes would most likely come in contact with the clone snails and the gene pool of that snail would be saved.  There is little or no chance of this happening in an aquarium unless you have more than one snail.

When you purchase a ramshorn snail from a pet store though, or get one from a private party, even if you get only one snail and take it home to a tank with no snails in it, the snail may lay eggs without a mate. This is because of auto-fertilization and the probability that the snail has been in contact with many other snails already is very high. Ramshorn snails are quite small, hence they are hard to handle when they are to young to mate, and larger snails are usually sold, which are of mating age. That means, unless it is too young to mate, then it probably has mated and can lay fertile eggs. When there has been an overabundance of food in the tank the ramshorn snails reproduction rate will go up. Ramshorn snails will overpopulate the tank at this point because the more food they have, the more offspring they can and will produce.

Ramshorn snails lay their eggs almost anywhere and everywhere. On the sides of the fish tank, on the filter, on plants, and even on the backs of their fellow snails shells. The eggs are covered in a tough jelly like substance and are laid below the water line. They will hatch anywhere between 12-40 days depending on water temperature and water conditions.

The natural lifespan of a ramshorn snail is anywhere from 1 to 2 years depending on living conditions. How do you know if your ramshorn snail is dead? Sometimes it can be hard to tell is your snails are just resting, sick, or have passed away. You can check to see if they are still with you by smelling them. If there is a foul odor coming out of their shell hen you will know they are deceased. You should do this regularly because any dead animal in a tank will start to make the tank toxic.

Ramshorn Snail Care

Ramshorn Snails appreciate a temperature range of 75-80 degrees. These snails will eat a wide array of vegetables and any decaying plant material, fish food, algae wafers, other snails and fish or snail eggs. Favorites are spinach, romaine lettuce, and algae wafers. Their water should be changed as you would a normal fish tank except when something goes wrong and they start climbing out of the water, then you know its time for a change. Tap water should be treated with aquarium water products to remove toxins and metals. I like the people and pet safe variety like AmQuel+ and NovAqua plus. You will have to keep an eye out for dead snails too, because as they decay they release toxins into the water which can make conditions in the tank unhealthy.

Calcium is important for snails to maintain a healthy strong shell. The water can be supplemented with calcium in several ways. Some people use cuttle bone in the gravel of the tank. Cuttle bone is sold in most stores for birds to get calcium by scratching their beaks on it. You can just bury the cuttle bone half way in the gravel and soft side up, and the snails will absorb the calcium through their foot. Or you can crumble it and distribute it through the gravel so it is not as noticeable. Another way to supplement calcium is with products found at your local pet store like, "Kent Marine Liquid Calcium". Another inventive way to supplement calcium in your fish tank is to bake eggs shells, without the inner peel, at about 350 degrees until they are brittle and then they can be broken up and sprinkled in the snail tank.

Where are there Ramshorn Snails for Sale?

Sometimes you can get small, unseen varieties of ramshorn snails mixed in with aquarium plants you buy at your local pet store, but snails are usually not sold by themselves. You can buy ramshorn snails online through auction sites like Ebay, and AquaBid.com.

Snails love their diet supplemented with algae wafers. You can see in this picture some of the snails shells are becoming thin and cracked from insufficient calcium levels in the water.
This one is eating algae off the side of the tank. See his little mouth.

Be a Responsible Aquarium Owner

Don't Accidental Release Exotic Species Into Your Surrounding Ecosystem:

Great care should always be taken when changing aquarium water so that none of the aquariums inhabitan'ts are released into your local environment. Make sure and inspect your aquarium water changing bucket to see there are no hitchhikers in the dirty aquarium water you just siphoned while cleaning your fish tank. Never pour aquarium water down storm drains or into rivers, lakes or streams.

Most of the little creatures and plants we keep in fish tanks are not indigenous to, or they do not naturally come from, the area in which we live. Many foreign species of aquatic plants and animals have shown up all over the world in places they shouldn't be, where they have no natural enemies. This means their populations can explode and they can kill native animals, to the point of extinction, and wreak havoc on the natural eco-system. This is only one way a non-native species can damage an ecosystem. It is a big responsibility to keep an aquarium thriving, but it is also very important to be a responsible pet owner.

Don't mind me buddy, I'll just crawl right over you.

My mom was an enthusiastic aquarium lover. Your article on the rams horn snail was very interesting and the photo's are great. The info about the clown loach being a snail eater was especially interesting. I will remember that when I get my aquarium started.

Thank you for the kind words, I do like my pictures. Knowing about the clown loach is a good thing because the snails can get out of control, but watch out or the loach will eat all of the snails, if they are the right size. Some people like that because they don't want snails, but I like the snails for pets.

hi what r ramshorn snails

Kelly A 22 months ago

Just a word of wisdom to all. The article says they need two snails to reproduce and that is not true. Ramshorn snails reproduce asexually which I found out the hard way. I read this article and thought I was safe if I got just one and now my tank is infested. I do love to watch the snails they are interesting little creatures but please be advised they will reproduce and reproduce and reproduce. Your best bet for a single snail in an aquarium is a mystery snail. They reproduce sexually so as long as you only have one, you will only have one.

 22 months ago

This is very true. I thank you for bringing this to my and everyone's attention. I should have mentioned in the article that when purchasing or obtaining snails from a source, the probability of the snail being in contact with other snails is very high. From what I have read they are hermaphrodites, so they have both sex cells, but need to exchange them, but I am sure they could also procreate on by themselves as well. I am going to revise the article to mention this because my last intention is to mislead anyone with information. Thank you again for bringing this to attention, and I do hope you were not inconvenienced too badly by the ramshorns. Apple snails are lovely as well, I hope to get some one day. I don't think they mix with the ramshorns though. They are much bigger. Maybe they will rid your tank of the ramshorns? Anyway, good luck to you, and I hope you were not too troubled by the whole ordeal. Cheers.

how do you know if your ram horn is dead?

Tamarind profile image

Tamarind Hub Author 21 months ago

They do hide in their shells sometimes, resting or if they are sick, and it is hard to tell if they have passed. One thing you can do is take the snail out and smell it. If there is a foul odor you will know it is gone. There may be foam or bubbles in the shell as well.

jason 21 months ago

do the snails really NEED a 75 to 80 degree temperature

Tamarind profile image

Tamarind Hub Author 21 months ago

I'm not sure if they absolutely need this temp to survive, but I think it is their preferred living temperature. At least for the type of ramshorn snail that is usually found in freshwater aquariums. There are different kinds of ramshorn snails, the ones that live in rivers are adapted to the temperatures of the region.

iluvfish 20 months ago

my snail,Millie has two clutches of eggs and im pretty sure she was never with other snails because i bred her/him myself,and if snails r hermafridites then they dont need two to have baby snails

Tamarind profile image

Tamarind Hub Author 20 months ago

This is true. The gene pool of the snails will be weak and eventually die out, but they can lay eggs on their own and have babies on their own. I have had snails that don't lay eggs at all or every once in awhile. And some that lay eggs constantly. I would say how reproductively productive the snails are has to do with a lot of factors. It probably has to do with the condition of the tank and availability to food. I am very happy so many people are interested in these snails and how much learning is going on here. This information adds to this article and is greatly appreciated.

very good page gave some great info. I'm still wondering if the water in the tank is bad cause some snails hang around at water level i have like 50 ants about 10-20 are always at the top but the other 30 and the 4 stickleback stay lower...is the water ok or bad?

snailiac 19 months ago

ants....lol got carried away with the other tab page...sorry i meant snails (ramshorn)

Tamarind profile image

Tamarind Hub Author 19 months ago

lol. I knew what you meant about the ants:)The ramshorn snails do tend to kind of anchor at the top to rest, and some don't. My snails do the same thing, hang around the top. They also seem to huddle behind aquarium objects like filters and plants when they rest. It is in my experience when the water in the aquarium is getting toxic, the snails will all stay at the top of the water line and then even crawl past the water line and stay out of the water. So, from what you say, your water is probably okay.

Hey there, I have 2 Ramshorn snaills that mated big time my tank is covered with around 30 patches, it's been about 3 months and nothing is happening to them, there are dots in every one but it has been so long sonce they are meant to hatch, what should I do!? get rid of them or leave them for a further couple of months !

neoyyf profile image

neoyyf 6 months ago

@Kai If the dots look milky, you can scrub those off because those are dead. If you want them to hatch, leave the rest and they will hatch in due time. Babies are the size of pinheads so you wont see them until they are about 0.5mm if you look really carefully

@Tamarind Your pictures are mainly of blue ramshorns, do you have any for sale? I only have red ramshorns and I do sell them occasionally to keep numbers down

I am interested in getting an apple snail (mystery snail) to add to my tank...it isnt a larger breed of apple snail but i just wanted to check to see if it would be compatable with my ramshorn snail?

Tamarind profile image

Tamarind Hub Author 2 months ago

I have read that mystery snails will eat ramshorn snails. I think it may also have to do with how big your tank is and how much food is available. If you have a big tank the ramshorns may be able to escape etc. I have not tried this combo yet, but I do love mystery snails and I would be interested in your findings on this matter if you take the chance:)

    Juvenile Ramshorn Snail
    Note the spots on the shell of the smaller one, and more hidden on the larger snail.
    If you look close you can see the bubble in the shell.
