What Are Aquarium Snails?

Aquarium snails are small creatures that eat algae and other types of organic debris. Some species are quite attractive and valued as inhabitants because they can be beneficial to the overall health and balance of an aquarium. Therefore, there are frequent cases that aquatic hobbyists decide to keep this type of pet.

However, as with everything else, there are exceptions in this case. Namely, not all aquarium snails are equally desirable, attractive, and interesting to observe. So, there are some types of snails that reproduce fairly quickly, introduce imbalances and even damage your underwater world.

Unplanned snail outbreaks most often indicate an imbalance and loss of control over conditions. Worst of all is that it mostly appears suddenly, as a surprise, and hobbyists usually don’t know where they came from.

“Good” Vs. “Bad” Aquarium Snails – What’s The Difference?

Almost all problems with snails can be avoided when a person knows their characteristics and how to avoid accidentally introducing them to the tank. In addition, it is important to know your own tank as well as do proper research to make sure you are buying the right types of snails for your aquarium.

“Good” aquarium snails help remove algae, and in addition consume uneaten food, dead plant matter, and other detritus that accumulates in the aquarium. It is also very interesting that in search of food they tend to dig through the substrate, thus preventing it from compacting and becoming anaerobic.

Lately, they are becoming more and more popular as pets because of their bright colors, intricate patterns, and unusual shapes.

Although they are often called “bad”, there are actually no bad ones, only those that can be multiplied unchecked and as a result overrun an aquarium. Most hobbyists, especially novices, get scared when they realize that hundreds, if not thousands of these little beasts are taking over their aquarium tanks. Their appearance is quite unpleasant because they can place a burden on biological filtration as well as clog filter intake tubes.

However, you don’t need to panic as there are numerous ways to get rid of aquarium snails. Read more below.
