If you’re interested in sharks, you’ve thought about having one as a pet. Even though having an actual shark as a pet is virtually impossible, there are lots of freshwater sharks for fish tanks which can thrive well in the aquarium at your home.

Technically, these species fish aren’t sharks. They are big, shark-like fish usually belonging to the catfish or carp families. That said, they look and often behave like sharks, which is how they won their name.

Can Freshwater Sharks For Fish Tanks Be Kept In a Home Aquarium?

Many freshwater aquarium sharks are not true sharks, but Cyprinid family members, including Rasboras, Danios, Minnows and Barbs,. There are also several catfish who got the nickname of “shark” due to their physical appearance and feeding habits. Such fish are all involved and will certainly encourage some movement in your tank.

Sharks, unlike other freshwater fish, do not respond to other mates. Rather, they respond to physical surroundings. It could take several weeks or more, depending on the tank’s plants and decorations. While they’re very active, it takes a much longer time for a new shark to be confident in its new environment than most other fish, and a pet owner may not see their shark for a long time.

When a shark gets confident, it will claim a territory and usually remain there. If the tank is small, the fish will attempt to assert dominance over the entire aquarium and become aggressive or, at least, start nipping. When you plan to keep a shark in a smaller tank (under 55 gallons), hold it with fast moving fish and fish without long fins.

Nearly all freshwater aquarium sharks fall into one of two groups: aggressive Cyprinids (Minnows and Carp) and predatory Catfish. We put together a full list of the best freshwater sharks to have in your aquarium. Some are tall, some little, but they’re all incredible.

Black Sharkminnow

It’s evident when young that Black Sharkminnow is a close relative to the first two Shark species. This Shark, however, grows huge compared to 24 inches typical for aquarium species and up to 36 inches in nature.

Black Sharks are popular and attractive enough to be pursued by a fisherman for both sport and food. Black Sharks are somewhat rare in pet trade, but often marketed to naive aquarists who don’t know they’re going to outgrow anything but the largest aquariums.

The Adult Black Sharks have floating extensions of the fin and a purplish black color that is distinctive. They are strong, weighing up to 25 lbs!

Cyprinids as a whole tend to be omnivores and are hardy aquarium fish. Considering the Black Shark’s size and aggressive nature, it ‘s important to pair them with fish that are quick enough to get out of the way so they have enough space for them to claim in an area.

Iridescent Shark

They are dynamic and vividly colored, with a purplish black iridescent mixed with light white tones. Nevertheless, Iridescent Sharks can attain 3 to 4 feet in length and are a schooling fish.

Iridescent Sharks are tightly linked to the Mekong Giant Catfish (Pangasianodon gigas) which is up to 10 feet long and is one of the biggest freshwater species of fish in the world.

Silver Apollo Shark

The Silver Apollo Shark is more passive than the Red Tail Shark and Bala Shark. It requires mildly acidic water, pH between 6.0 and 6.5 and temperature range 66 ° F to 79 ° F.

It’s a jumping shark. Keep in a lid tank at all times. The Silver Apollo shark is much more likely to leap out of a tank within days or longer.

It will gradually settle in and show a much less erratic swimming pattern, but if spooked, it can swim full speed into the side of the tank.

This is among the few freshwater aquarium sharks to be considered a surface resident. It’s an ultra-fast eating machine that isn’t particular about what it eats, so it may prevent less agile fish from having a meal. These fish can benefit greatly from bloodworm snacks or other live food.

Rainbow Shark

Rainbow Shark

The rainbow shark is another freshwater shark that is technically a catfish. They ‘re a perfect addition to a tank.

Since they like many hiding places, make sure to give them plenty of thick vegetation, caves and dens to explore.

Rainbow sharks are very territorial with other sharks, particularly red tails. When you’re searching for tank mates, seek fish larger than them with similar temperaments. They shouldn’t be too violent, but still keep their own. Rainbows will torment friendly fish at all costs.

Though Rainbows prefer tank bottoms, they have sensitive barbels about their mouths that can be easily hurt. Choosing the right substratum is important to prevent injury. Use only sandy or smooth substrates, as larger, rougher rocks may cause damage.

Such fish prefer to live on the tank ‘s bottom, but will explore anywhere. Believe it or not, they ‘re pretty decent jumpers, so make sure you ‘re covering the tank top.
