Mystery snails are another tank cleaner. Like nerite snails, they eat algae, dead plants and uneaten fish food, but they will not eat dead fish since they are herbivores, and they never eat live plants although they are hungry. They are easy to care for and you don’t have to worry that they will bother your fish or cause damage to things in your tank. But there is one thing important, you need to buy a lid for your aquarium because they might get out of the tank.

How to take care of snails
Now we have known the average lifespan of many snails, but they can live much longer in a proper environment. So what should we do to take good care of them?
Here are some suggestions:
- Provide them with the proper fish tank: According to the length a snail can reach, choose the best tank for it. Normally, a tank of at least 5 gallons is necessary, but if you pick up snails as the tank mates of your fish, the tank size should be determined by the size of your fish.
- Make sure your fish tank is clean: A clean environment is important, not only for fish but also for creatures that live in water.
- Feed them with plants and vegetables: They can provide the nutrients that algae, uneaten food or debris do not contain.
- Keep them away from salt: Salt is fatal to snails, it will make them feel stressed and might kill your snails.
- Keep the water temperature at 65-82℉: Snails need a warm environment to live and thrive
- Change the water regularly: Dirty water contains a lot of toxins which is detrimental to the health of the snails.
Tips for keeping a snail
- You can know the age of a snail by counting the rings in its shell, just like counting annual rings to know the age of a tree.
- Mystery snails lay eggs out of the water, so prepare a space free from water for them if you want them to reproduce in your tank.
- The shell is important for a snail, and you should make sure the water in your tank contains calcium so the snail can grow its shell.
- They sleep whenever they want, and it’s not strange to see them sleeping for 2 or more days. So do not think they are dead when they don’t move around.
- Most snails carry parasites, so if you keep them with fish, make sure your fish are free from the parasites.
