13 Best Types of Freshwater Aquarium Snails

If you are an aquarium enthusiast and love keeping fish as pets, you should be quite familiar with freshwater aquarium snails. You could be someone who loathes them, as certain species act as pests and intruders in an aquarium, just like weeds do in a garden, or you could be someone who might be intrigued and fascinated by them.

No matter what you think of freshwater snails, it’s likely a good idea to buy some for your aquarium. Despite popular belief, not all species of snails are actually bad for your aquarium. They are wonderful creatures that can help you actually keep your tank clean and save your equipment. They feed on organic matter, help keep the substrate fresh, and prevent the production of anaerobic gasses that can be detrimental to the health of the fish in the tank.

Plus, there are many different colorful species with gorgeous patterns and different shapes. They can be kept as pets on their own or as tank mates that can coexist with a variety of fish and invertebrates while keeping the aquarium spotless.

However, it is also true that some snail species reproduce rapidly, crowd the tank and eat up the aquarium plants. Therefore, it is essential to know the different types of freshwater aquarium snails that are best suited for your tank and those that would make great pets without causing chaos.

So, let’s get straight to it!

It is easy to prevent them from reproducing rapidly and creating a nuisance.

They live longer than other snails and are usually quite active, even around nighttime. If they are kept well-fed, they will help keep your tank clean by eating up dead debris.

FAQ

Are snails good for your fish tank?

Yes, and no. Snails are good for your tank if they do not reproduce rapidly. Snails that produce sexually are great for this, as they do not crowd your tank and can even help keep your tank clean by eating up dead matter, algae, and other debris. Hermaphrodites snails may make great pets only if you are able to control them and are willing to put in the effort to avoid overpopulation.

Can snails live in freshwater aquarium?

Yes, snails can survive in your freshwater aquarium as long as the pH levels and temperature are within suitable ranges. It’s also essential to make sure they have the food they need to survive around them. Different snails feed on different matter, so make sure to do your research before buying a particular type.

Is it bad to have a lot of snails in the fish tank?

Mostly, yes. Unless you can take care of it, a tank with a ton of snails does not create a suitable environment for the fish and invertebrates living in it. Moreover, an overabundance of snails may damage your filter, eat aquatic plants, and slowly destroy other equipment through overcrowding.

How did a snail get in my fish tank?

Unless you put them there yourself, there are a ton of ways a snail can suddenly appear in your aquarium. Most snail eggs are usually transparent, so they might have stuck to plants and decoration you may have recently put in your tank.

How long do aquarium snails live?

All types of snails have different lifespans, with their age generally not going past 5 years. Some may even live for only a year, whilst others may survive about two to three years.
