Cardinal tetra has a fascinating appearance. It is one of the most popular aquarium fish due to its beautiful, deep red color.

The cardinal tetra is a type of fish native to the Amazon River basin in South America. It is a small, colorful fish that can grow up to four inches long. These fishes live for around four to five years.

Cardinal tetra is a freshwater fish that prefers a temperature between seventy and eighty degrees. Therefore, they need vegetation and a tank with open space for swimming. Along with this, these fishes also require sufficient light and a dark substrate.

These fishes are overall peaceful and can live in community aquariums provided they have the right conditions. But it would be best if you did not house them together with fish that may nip their fins or bully them otherwise because of their small size.

How Can You Protect The Original Appearance Of Cardinal Tetra?

This bright redfish has a black line that runs through its eye and down its body. In addition, the male cardinal tetra is even more brilliant than the female, making it a popular choice for home aquaria.

If you want to protect the original appearance of cardinal tetra, it is essential to provide them with an environment that closely mirrors their natural habitat. So, some tips for you might be:

Select A Bigger Tank

You should make sure you’re purchasing a large enough tank for your cardinal tetras. The best tanks for these fish are around 20 gallons, and if you’re planning on keeping a larger school of cardinal tetras, then I’d recommend going even more prominent.

Choose Slightly Soft Water

Generally speaking, most freshwater tropical fish will do well in neutral to slightly acidic water with a pH between six and eight. However, the cardinal tetra is an exception to this rule as it does best in somewhat soft water with a pH of around six.

Provide Lots Of Plant Life

Cardinal tetras love lots of live plant cover, so be sure that you’re providing your cardinal tetra fish tank with plenty of lush greenery like Amazon swords and other similar plants. But, of course, you can also use artificial plants to achieve the same effect.

Use A Heater And Filter

Make sure you have a good quality heater and filter in your tank, as these are essential pieces of equipment for keeping tropical fish healthy and happy. The cardinal tetra is a hardy fish that can withstand most water conditions, but it’s always best to err on the side of caution.

Choose A Suitable Diet

Ensure you’re feeding your cardinal tetra fish appropriately to ensure they stay in tiptop condition and don’t lose their bright colors. Your local pet store should recommend suitable foods for these fish.

Make Sure You Choose Males Over Females

Be sure you choose male cardinal tetras over females if you want to protect the original appearance of your fish. The female cardinal is duller in color than her red-striped mate.

It’s also worth mentioning that males are typically more aggressive and active than their female counterparts, so keep this in mind when you’re thinking about stocking your aquarium with cardinal tetras.

Be Careful With Your Water Quality

This species requires pristine water quality to thrive and maintain its brilliant coloration. Therefore, test your water parameters regularly and take corrective action if necessary.

Add A Bit of Salt To The Water

Tetras are generally very sensitive to salt, but the cardinal tetra is an exception to this rule. These fish do just fine with a bit of aquarium salt added to their water – between one and two teaspoons per ten gallons should be sufficient. However, you should avoid using salt in your tank if it contains any live plants.

Some Of The Problems With Cardinal Tetra

Despite the beautiful appearance of Cardinal Tetra, there are some problems with this fish. These include:

  • They are susceptible to water conditions and can be challenging to keep healthy in an aquarium.
  • Cardinal Tetra requires a lot of space, so they are not ideal for small tanks.
  • They often become shy and inactive when kept in groups smaller than six fish.
  • Male cardinal tetras harass females and other males.
  • They tend to be a bit expensive, as they are not very common in the pet trade.

Conclusion

In conclusion, the best way for someone who wants to keep cardinal tetras is by doing research first on their needs and requirements before purchasing them. It is also crucial for you to select a bigger tank, choose a suitable diet, and provide plenty of plant life.
