What is a Freshwater Aquarium Shark?

While the majority of the species fall into the ocean-swimming category, there are a few that one can keep as pets in a freshwater aquarium or pond, and these are widely known as freshwater aquarium sharks.

All the fish that fall under the Aquarium shark category are Native Tropic Catfish or Cyprinids. They are mostly mid-water or bottom dwellers, and they are all active fish.

All aquarium sharks have dorsal fins and forked tails and are generally easy to keep and breed as long as they are provided ample space to swim around.

Most Common Types of Freshwater Shark Species For Your Home Aquarium

Though all aquarium sharks are generally easy to keep and are pretty low maintenance, not all are ideal for new aquarists. Sharks, no matter how small, definitely need their space.

Many also tend to prey on other smaller fish!

So, if you don’t want your pet to eat your other pets, you may want to choose who to pair up with your sharks very wisely, and we are here to help you.

Here, we bring you the 11 most common types of freshwater aquarium sharks.

How Big Can Freshwater Sharks Get

Freshwater aquarium sharks can get quite large, with some of them growing to around four to six feet as well. Thus, you cannot keep all the species in freshwater recreational aquariums.

What Is The Biggest Species Of Shark You Can Keep In Your Aquarium?

It depends upon your aquarium size. If you can get yourself a six-million-gallon aquarium, you can even keep a whale shark. However, that is not advisable, nor is it practical. Some of the largest freshwater aquarium sharks you can keep in your home are Bala Sharks, Iridescent Sharks, and the Chinese High-Fin Banded Shark. But you will have to get the largest available tank to house these fish.

Are There Any Small Fish That Look Like Sharks?

Essentially, sharks cannot live in freshwater. All of the fish mentioned above belong to the catfish category. You can either get the smallest ones from the list, which grow up to around four inches, such as the Roseline torpedo shark. Or you can look at other fish from the catfish family.

Care Tips for Your Pet Sharks

Different sharks have different requirements. To ensure your shark thrives in your aquarium, you need to understand their requirements, including water pH level and habitat requirements.

Most sharks are territorial and aggressive, so make sure you provide them plenty of space to move around in. You will also have to include plenty of hiding spots, such as caves or greenery, to offer them hiding spots. As long as you ensure they are with like-minded tank mates, who they cannot prey on, and feed them timely, caring for your most sharks is relatively easy.

We suggest that you consult the pet store owner before purchasing sharks, as handling them can be quite challenging for beginner aquarists.
