What To Look For When Choosing Your Betta Fish Tank

Before moving forward and adopting betta fish into n aquarium, one must conduct a thorough research about their habitation needs and purchase the tank accordingly.

Since betta fish live in shallow, slow-flowing, or stagnant waters, they are accustomed to this ecology. The tank should aspire to imitate this ecology and provide a comfortable space for the fish.

Tank size, dimensions, filtration amenities, and lighting are a few things to consider before getting a tank for the fish. One can include plant life in the betta fish tank as they thrive when surrounded by a natural environment.

Betta fish tend to jump from one area to another in their natural habitat, searching for oxygenated water. Betta fish in a tank tend to jump out of the water’s surface. Therefore, their ideal tank should also have a lid to prevent accidental deaths.

Tank Size

Tank size is the most crucial feature to look for while choosing a tank for a fish of any specie. The tank needs to meet the physical requirements of the fish because it is going to be their home as long as they live.

Many people do not give enough consideration to the tank size and get a tank that is just slightly bigger than the fish. Very few people are aware that a small tank significantly reduces the life span of the fish because it does not get enough space to move and swim.

Small tanks with an approximate one-gallon capacity are cheaper, but they are like a death sentence for the fish. The fish should not have to exist for the sake of existing; it should get to thrive in its aquarium. Anyone who intends to keep a fish tank would eventually want to decorate it.

Small tanks do not have enough room to add decorative elements. A tank with a capacity of five gallons or more would allow the betta fish to thrive and live up to their maximum life span, and it would also have ample space for decorations of choice.

Despite its visual appeal, one should never keep betta fish in a vase because of the apparent lack of space.

Do Betta Fish Prefer Long or Tall Tanks?

Five-gallon tanks come in various dimensions, and it is essential to understand the nature of the fish before investing in the tank. One can accommodate five gallons of water in numerous combinations of dimensions.

Choosing the correct measurements can be intimidating because a wrong choice can lead to poor health of the fish and premature death. Betta fish are accustomed to living in shallow water, and they move along the horizontal axis rather than the vertical axis, i.e., left and right over up and down.

Therefore, betta fish would not benefit from tall tanks as the height would not provide them any range of motion. Contrastingly, a long tank would have a larger horizontal surface area. These dimensions would give more space for the betta fish to swim left and right, allowing it to thrive and live long.

Moreover, Betta fish regularly come to the water’s surface to gulp air and feed on larvae and insects. They even have an upturned mouth to help them successfully hunt their prey.

Their beautiful flowing fins are amusing to look at but hinder them from swimming too high up. These characteristic conditions also emphasize why a betta fish tank should be longer and not taller.

Filtration

Filtar

Betta fish are highly resilient and have evolved considerably. They have adapted to living in stagnant or polluted waters with low oxygen levels.

They are not solely reliant on the oxygen dissolved in water and come up to the top of the surface to gulp air as and when needed. These adaptations help the betta fish to survive in drought-prone areas. Because of these adaptations, people believe that betta fish can survive in bowls or tanks without a filtration system.

But this is a false assumption because keeping betta fish in a filterless tank can cause premature death, fin rot, stress, and other ailments. A person can survive in dirty surroundings, but survival does not mean that they are thriving and happy in that unsanitary surroundings.

Therefore, having a filter in the tank is always the preferable option for housing betta fish. The fish will thrive even in a low flow filter. High-flow filters tend to be overpowering and can push the fish around.

LED Lighting

Betta fish can thrive under proper lighting. Like most living organisms, they need both light and darkness to function optimally. Keeping their aquarium under artificial light rather than direct sunlight is preferable because the latter can increase the aquarium’s temperature and give birth to algae.

To maintain proper temperature and sanitation, artificial lights that mimic sunlight should be used. LED lights do not cause excessive heating; therefore, they are ideal for betta fish tanks.

Besides no temperature fluctuation and algae growth, LED lights also encourage vitamin D nutrition in the fish. The height, spectrum, color rendering, and angle of the light should be considered while deciding on the appropriate LED lighting.

Style

It has already been established that betta fish need considerable swimming space along the horizontal axis to remain healthy and stress-free.

Therefore, any tank with a lower height and longer length and breadth should work perfectly, and the size of the tank should gain priority over its style.

The shape has more significance for the human keeping the fish as their pet. As long as the tank is large enough and has sufficient horizontal space, the shape or style depends upon the aesthetic preference of the person.

There are numerous varieties of tanks available in the market, like traditional aquariums, advanced bio tanks, round tanks, curved tanks, bow front tanks, or tanks with dividers. The style has more significance for the overall decor of the room and the observer than the fish itself.
