Aqua Creations discusses keeping sharks in a fish tank
There are few creatures that capture the imagination quite like sharks. With Aqua Creations, the custom aquarium experts, you can explore the endless possibilities of including sharks in a fish tank and immerse yourself in the stunning marine sanctuary where the graceful movement of sharks adds both beauty and excitement.

Why Keep a Shark in an Aquarium?

Integrating sharks into your custom aquarium creates an aesthetic appeal that transforms the space with elegance and intrigue. Sharks, with their captivating allure, add a dynamic presence to the aquarium setup. Their sleek, graceful form and enigmatic behaviors offer endless fascination for observers.

The shark’s distinct appearance makes it an instant focal point, serving as a conversation starter, and sparking curiosity and admiration from viewers. Although sharks’ bodies are made out of cartilage rather than bones like other fish, they are in fact fish. They live in water, but their behaviors differ from those of typical aquarium fish. This not only provides endless interest but also opens the door to educational opportunities.

Different Types of Sharks for Aquariums

Sharks bring unique beauty and movement to an aquatic setup. There are several shark types that thrive in aquariums. These species of sharks are generally smaller, more docile, and adaptable to aquarium life. The type of sharks for aquariums will depend on whether it is a freshwater or saltwater tank. Here are some of the best sharks for home aquariums:

Freshwater Sharks

Freshwater sharks are not true sharks, but they have similar appearances and swimming patterns that earned them the nickname. Popular species include the Rainbow Shark and the Red-Tailed Shark.

Appearance
They have a shiny, iridescent color that gives these fish their name. Juveniles have a black stripe along the lateral line and a second black stripe below the lateral line. They actually look more like sharks than many real marine shark species

Grow up to 6 inches and need lots of hiding space
Compatibility with other fish
Peaceful in the home aquarium but if stressed, their first instinct is to flee; a blind dash can cause injury in an aquarium environment. These injuries may result in the fish sinking to the bottom, where it may lie on its side or back until it recovers
Aggressive, especially towards their own species and smaller fish, but can also be paired with other fish of similar size or schooling fish
Required water temperature
75-81°F (24-27°C)

Saltwater Sharks for Aquariums

Saltwater sharks are true shark species. Unlike the smaller freshwater species, saltwater sharks for home aquariums need much larger swimming spaces due to the size they grow to as adults. Species of saltwater sharks that are suitable for aquariums include Bamboo sharks and Epaulette sharks.

Challenges of Keeping Sharks in Aquariums

Keeping sharks in a fish tank requires careful consideration to ensure the well-being of both the shark and other tank inhabitants. Here are a couple of challenges to be aware of:

Tank Size for Sharks in a Fish Tank

Sharks need ample space to swim freely. Planning ahead for the sharks’ full adult size is essential for providing an environment that mimics their natural habitat. Underestimating the required tank size can cause distress and health issues.

Sharks’ Compatibility with Other Fish

Do sharks eat other fish in an aquarium? Sharks can exhibit aggressive tendencies, particularly when housed in a cramped environment or paired with incompatible species. Selecting the right tank mate is, therefore, essential. Smaller fish can become targets, so similar-sized fish are generally included in this dynamic display.

Managing Aggression Displayed by Sharks in a Fish Tank

Sharks are often territorial and can display aggressive behaviors. To minimize aggression, here are some important points to consider in your setup:
  • Provide Enough Swimming Space: Overcrowding can increase stress and aggression. An experienced aquarium designer will ensure your shark aquarium contains open swimming areas and designated hiding spots.
  • Choosing Compatible Tank Mates: Sharks need to be paired with non-aggressive fish that are similar in size so that they won’t provoke them.
  • Create Proper Tank Structure: When installing the aquarium, adding caves, rock formations, and plants or corals provides visual barriers that allow the fish to establish territories and reduce conflict. This ensures a secure and harmonious environment for your sharks.
  • Monitor Feeding Habits: Hunger can lead to aggression. Providing a well-balanced diet at regular intervals prevents sharks from seeing tank mates as potential prey.
