8 Fish That Eat Snails But Not Shrimp Aquarists Should Know

Due to their rapid reproduction, specific freshwater snails, such as bladder snails, may become a problem in aquariums.

These crawlers frequently sneak into tanks on decorative items and aquatic plants without being detected. 

How to deal with these creatures which share the same tank with shrimp? It’s a great idea to add fish that eat snails but not shrimp to that aquarium!

Let’s dive into this article to learn more about these species!

The Importance Of Snail-Eating Fish

Hitchhiker snails that find their way into a well-established ecosystem may interest inexperienced aquarists.

However, experienced experts know these crawlers can make maintenance more complicated and challenging. 

Snails reproduce quickly, and various species can breed alone without a partner. They can deliver up to 50 fertilized eggs, resulting in a growing population.

Once the crawlers in the second generation begin to reproduce, they can swiftly take over your aquarium.

It’s your tank’s biological load that’s the cause of the snail overpopulation problem.

Your aquarium’s size doesn’t matter. Maintaining the water’s parameters will become more challenging as more live things appear.

Many crawlers consume algae, decomposing plant materials, and residual food. However, they’ll undoubtedly generate a considerable amount of waste.

Although it may not look like much, the impacts of the waste will have catastrophic repercussions on the ecology when faced with an overloaded tank.

You can use a filter, but this equipment is unsuitable for a shrimp tank as these little organisms may be sucked into the system. 

For all the above reasons, adding some fish that eat snails but not shrimp to your aquarium is best. 

These creatures can help reduce and control the snail population without causing harm to tiny shrimp.
