  • Maintain a stable temperature between 24 and 27 °C with a suitable heater.

Ideal aquariums for Betta fish

One of the most beautiful and striking fish is the Betta splendens fish, also known as the Siamese fighting fish. Its intense coloration and majestic fins not only make it one of the most popular ornamental species, but it also has characteristics that make it great for beginners in the aquarium world. This fish, originally from Asia, lives in swampy regions of countries such as Thailand, Vietnam and China. Thanks to its ability to adapt to low levels of oxygen in the water, it is a perfect choice for those looking for a pet of moderate maintenance.

Unique Features of Betta Fish

The Betta fish has a special organ known as labyrinth organ, which allows them to breathe oxygen from the surface, much like a mammal would. This evolutionary adaptation allows them to survive in environments with poorly oxygenated waters, such as flooded rice fields and swamps. Although this may give the impression that they can live in minimal conditions, the ideal is to provide them with a space suitable to ensure your well-being.

The ideal aquarium for the Betta fish

Although Betta fish can survive in small containers, this is not recommended in the long term. A small space increases your stress level, which can reduce their life expectancy. Ideally, they should be offered an aquarium of at least 10 liters, but one of them is highly recommended 20 liters or more to ensure their comfort and allow for freer movement. The shape of the aquarium also plays an important role; rectangular aquariums are best, as they make it easier for Bettas to climb to the surface without effort.

Essential accessories for the aquarium

  • Filter: Although Betta fish do not need a constant flow of water, a gentle filter is essential to maintain water quality. Opt for sponge or adjustable flow filters that do not generate strong currents.
  • Heater: Maintain a stable temperature between 24 and 27 ° C is crucial. Adjustable heaters are the best option.
  • Lighting: A soft light is enough to mimic the natural cycle of day and night, but avoid overly intense lights that can stress the fish.

  • Parameter measurement: Monitor pH (between 6.5 and 7.5) and the levels of nitrites and nitrates.

Aquarium decoration and enrichment

The aquarium environment should not only be aesthetically pleasing, but should also provide a stimulating environment for the Betta fish. Live plants such as java fern or Anubias They not only improve water quality, but also offer hiding places and resting areas. In addition, it is advisable to add decorations such as caves or shelters, always making sure that they do not have sharp edges to avoid damage the delicate fins of the fish.

Feeding the Betta Fish

Feed it with specific food for Bettas and supplement it with options such as mosquito larvae, daphnia or brine shrimp will ensure that it stays healthy and brightly colored.
