Tank Set-Up

Recommended Tank Size For Columbian Shark

Columbian sharks can grow up to 3 feet in length when fully grown. Therefore, it is essential to provide them with an adequately sized tank that will prevent overpopulation and allow enough swimming space.

  • If you plan to keep more than one shark, you will need to provide an additional 20-30 gallons per shark.

Appropriate Gravel And Substrate

Columbian sharks prefer smooth and sandy substrates as sharp edges in the gravel can damage their skin.

  • Small smooth river rocks
  • Pebbles

When selecting the gravel for your aquarium, you should avoid sharp-edged gravel as mentioned earlier. Instead, go for a smooth-edged, rounded, or oval-shaped substrate.

  • Ph: the ph level in the water should be kept between 7. 0 to 7. 5.
  • Hardness: water hardness should be between 8 and 12 degrees.
  • Ammonia and nitrite levels: these should be kept as low as possible, and the ideal level is 0ppm.

Necessary Equipment For Proper Filtration And Water Quality:

Given that the columbian sharks are sensitive to water quality, it’s important to have the right equipment for proper filtration and water quality in the aquarium.

  • A high-quality filter that is rated to handle two gallons of water per minute. This ensures that all waste byproducts are removed from the water.
  • An aquarium heater that automatically maintains the water temperature within the desired range.
  • A thermometer to monitor the water temperatures
  • A water testing kit to measure the aquarium’s water parameters, including ph, salinity, and temperature.

Setting up an aquarium for the columbian sharks requires careful consideration to ensure that all their needs and requirements are appropriately met.

Interacting With Other Fish

Columbian sharks, also known as tri-color sharks or tri-color catfish, are popular aquarium fish due to their distinctive appearance and active behavior. However, before keeping any aquatic pet, it’s essential to learn about their care requirements to ensure a healthy, happy life.

Interactions between various fish species in the same tank can be tricky, and columbian sharks are no exception. So, let’s delve into the topic of compatibility and tank mates for columbian sharks.

Compatibility With Other Fish

Columbian sharks are generally peaceful fish but can become territorial towards their own species and other bottom-dwelling fish. Hence, keeping multiple columbian sharks together is not recommended, especially in smaller tanks. These sharks may also nip at slower-moving fish species with long fins, such as angelfish, but generally not enough to harm them.

Ideal Tank Mates For Columbian Sharks

Choosing suitable tank mates for columbian sharks depends on their behavior and lifestyle.

  • Other peaceful, fast-swimming fish such as danios or tetras.
  • Small to medium-sized catfish species that stay in the mid to upper levels of the tank, such as corydoras or otocinclus.

However, it’s crucial to avoid aggressive or large species such as cichlids, gouramis, or larger catfish species like plecos as they can easily harm columbian sharks. Additionally, avoid keeping columbian sharks with small, slow-swimming species such as guppies or bettas, as they may become prey for the sharks.

Behavioral Insights And Advice

It’s essential to keep a well-maintained and appropriately sized tank for columbian sharks. A minimum tank size of 75 gallons is recommended, with plenty of swimming space and hiding places. These sharks are also active swimmers, so ensure proper filtration and aeration.

  • Feed them a varied diet consisting of pelleted foods, frozen foods such as brine shrimp and bloodworms, and live food occasionally.
  • Columbian sharks are nocturnal, so provide plenty of hiding places such as cave-like structures or plants to provide a sense of security.
  • Avoid touching or handling columbian sharks as they may become stressed and release harmful toxins.
