Buying Guide — Features to Look For

Form

The optimal shape is rectangular, because maintenance of this shape aquarium is easier, especially for beginners (try to clean the algae from the walls of a round jar, and you will understand how difficult this task is) and it is more challenging choosing equipment for aquariums of non-standard shape.

Volume

Here, you need to consider the required “living space” for each betta fish and think about the future. It is possible that, after a while, you will not want to limit yourself to only 3-5 fish. And if you set the scenery and plant plants, the free space will be too small for even such “Spartans” as Pisces betta to feel comfortable. If the possibilities allow, buy an aquarium with a margin of 25-50 in volume percentage.

Features

Aquariums made of Plexiglass are less preferable because this material is too “tender.” Its surface is easily scratched, even if you are very careful. Sellers can praise its quality as much as they want, but this material is not suitable for entry-level aquarists. And even Vushop specialists who carry out professional maintenance of aquariums admit that even they find it more challenging working with such banks. [2]

Betta is an exotic fish that likes a lot of light and warmth. [1] That is why it is recommended to have high-quality lighting and water heating so that your fish are comfortable. At average temperatures, which are sufficient for other inhabitants, betta fish are quite cold, become less active and their health deteriorates. Even considering that betta fish are unpretentious, regular maintenance of the aquarium is required; in particular, water substitution, pH control, mineral substances and algae control.

Large volume tanks are not required. It is optimal to choose an aquarium with the calculation of 5 gallons (18.93 l) per 1 betta. This is enough to make your fish as comfortable as possible, grow well and be playful. And, as you know, the right environmental conditions have an extremely positive effect, even on the color of fish, so you should be as aware of this as possible. 

The main thing is to maintain bio-balance. Tropical fish are more sensitive to the environment than others. That is why your main task is to keep optimal living conditions by all means. This applies to the water temperature, lighting and concentration of oxygen, nitrates, etc. Even better, if you have a few plants and snails, you get a double effect: the plants will release oxygen, and the snails will eat algae so that the water does not bloom. [3]

However, small aquariums still require special attention, as changes in water composition, temperature and stress factors are very pronounced in aquariums with a volume of fewer than 20 gallons (75.71 l). With a curious mind, patience and diligence, you can also create a beautiful and, most importantly, healthy nano-environment. This article will tell you how to achieve these results.

What to Avoid When Choosing Betta Fish Tanks?

There are often disputes about the size of the aquarium for betta fish. This topic has been a hot topic of debate among aquarists for many years and not without reason. Compact size is suitable for those who do not have space for a large model or organize a small living area at their workplace. But, undoubtedly, this is not the best place to keep most fish. 

In a small volume of water, it is easy to disrupt the biological balance and it is challenging to keep the hydro chemical parameters within acceptable limits. So, in nano-aquariums, the probability of fish death is high.

However, it is fair to say that technology in the aquarium industry is developing no less rapidly than in other industries, and it is incorrect to compare, for example, nano-aquariums of the ’90s with modern ones. 

Much new equipment has been introduced, ranging from LED lights to electronic water quality monitoring systems and nanoparticle filtration systems that allow all 3 filtration stages. Innovations have made nano-aquariums less susceptible to sudden fluctuations in water quality. 

However, they can still only be recommended to experienced aquarists. [4]

What Size Tank Does a Betta Fish Need?

One betta fish needs a rectangular or cubic aquarium with a volume of 5-gallons or more for a comfortable life, and the height of the aquarium should not exceed its width. A cover or cover glass is required. A filter and heater are also needed.

Females can be kept together. Most conflicts occur when new, adult fish are introduced. The aquarium for females should have a cover or cover glass and shelter.

What to Put in a Betta Fish Tank?

A pet store or market offers both artificial and live plants. Plastic does not require lighting and other care, but it does not contribute to maintaining bio balance, can cause injuries and exceptionally long fins. Low-quality products can release harmful substances into the water.

Live plants help establish and maintain biological balance. They look natural. But they need light; even not too whimsical species need 5-8 hours of light. Moderate lighting will suit mosses, ferns, etc.

Betta is a tropical fish, so it definitely needs a heater. The temperature of the betta fish content is from 75,2 °F to 82,4 °F. Aquarium heaters are equipped with thermoregulations, but the readings are not always accurate. Therefore, it is better to install a thermometer for additional control.

It is advisable to install a weak, internal filter, turning the flute and setting it so that the current is weak. Water aeration is not required — labyrinth plants, including betta, use atmospheric air for breathing.

Natural (solar) lighting is not recommended, because it promotes algae development and causes healthy temperature changes. The light should not be too bright. If necessary, you can shade about a third of the aquarium surface with floating plants.

Do not use natural seashells or corals as decorations and exclude items with sharp edges and protrusions. It is advisable to cover the aquarium with a glass lid/cover or fill the aquarium with water — not to the brim so that the betta fish does not jump out. [5]
