Reviewing The Best Betta Fish Tanks Right Now
Last updated: 20 Jul 2021
Also referred to as Siamese fighting fish or labyrinth fish, betta fish are known for their vibrant colors and flowing fins. They are sensitive individuals and can be territorial. The wild fish are native to Asia, where they live in the shallow water of marshes or slow-moving streams. However, many bettas sold as pets are bred on betta farms. Bettas are diurnal meaning they are active during daylight and they sleep during dark night hours. Since they are naturally carnivorous and prefer eating insects and insect larva, plant roots are not adequate for feeding betta fish. If you are considering getting a beautiful betta in your home or office, you’ll have to ensure you provide the optimal environment to give it a long and happy life. In this guide, we’ll help you select the best betta fish tanks in 2021 and give you some tips on how to take care of betta fish.

Just because fish are small and don’t bark, it doesn’t mean they don’t require attention, care, and space like any other pet does. Fish are very sensitive to their surroundings and can easily get sick or die if their environment is not similar to what they have in the wild. This not only includes having enough space but also the water temperature, water level, and surrounding flora. These aspects should all be considered when buying a betta fish tank as well as water filtration and lighting. In this guide, we’ll outline everything you need to know when setting up a home for your betta fish.
What To Consider When Buying Betta Fish Tanks
To meet the basic needs of your betta, you need at least 1 gallon of water per 1-inch size fish. When it comes to fish tanks, bigger is usually better. If your tank is meant for temporary housing, or you have a pretty small fish, a 1-gallon size tank could do the trick. For a permanent home for your betta, a tank of at least 2 to 5 gallons and up is recommended as the fish generally measure around 2.25 inches.
An aquarium filter is important to remove waste and decaying matter in the water that will poison your fish by producing ammonia if not removed. The filter also oxygenates water, making it more habitable for your fish. All fish, including betta fish, require clean and optimal water in their tank, which means a filtration system is an essential item to purchase with your tank. Some fish tanks come with a built-in filtration system while others need to have it separately installed. Filtrations can be mechanical, biological, or chemical.
Betta fish naturally live in still water without strong currents. Their delicate fins are not ideal for fighting waves or tides. When purchasing a filtration system it is essential to consider the flow created. Having a filter with flow control to prevent currents from forming in the tank is ideal. If that is not a possibility, you can control the flow by installing a flow baffle that could reduce currents for a more betta-friendly environment.
Bettas are tropical fish which means they are used to warm water and not happy in a cold environment. Ideally, the temperature of betta fish tanks should be between 78°F and 80°F (25.5°C - 26.5°C). Unless you live in a tropical climate where your fish tank is not kept in an air-conditioned room, you need to have an aquarium heater to keep your betta fish healthy. Buy a heater that is suitable for the size of your tank.
Many hobbyists who keep bettas go for a compact submersible tank heater. This can ensure that water temperatures don’t fluctuate, staying within the recommended temperature range.
Betta fish are used to shallow waters in their natural environment which means they get plenty of natural sunlight hours. This should be replicated as far as possible with artificial lighting in their indoor home. Eight to twelve hours of light in the tank is preferable since their activity will be affected by the shift between day and night. LED lighting is recommended for betta fish tanks to provide the optimal day-night contrast since it is economical and will not change the water temperature.
Plant and Decoration Set-Up
Decorating your fish tank with the right bottom covering and plants are not only for your own viewing pleasure, but most of all to provide a suitable, comfortable home for your fish. Since bettas swim on all levels of the aquarium, keep the substrate on the bottom to a finer substance as chunky or large pieces can injure your fish.
Good substrate choices for betta fish tanks are pea gravel, marbles, or sand. Living plants are the best choice for your bettas fish tanks, but you need to ensure the water plants will thrive in the same conditions and won’t be toxic to your fish. Good choices are java fern, dwarf hairgrass, and marimo balls.
Once their natural environment is set up inside the tank, you can add other types of décor as long as it is size appropriate for your tank.
Tank for Betta Fish FAQ
Will my betta fish get lonely?
Betta fish can feel depressed but they also experience stress especially when non-compatible fish in the same tank pick at their fins. If your fish is kept alone in a tank, simply ensure that the environment provides a lot of stimulation and exploration opportunities by including plants and caves.
What fish can betta cohabitate with?
If the fish tank is large with hiding areas, female bettas can sometimes live in a peaceful group. Other species that some male and female betta can live with include Cory catfish, kuhli loaches, guppies, snails, and ghost shrimp.
Can you use tap water in your betta fish tank?
Tap water contains chlorine and chloramine that is not suitable for fish to live in. Water needs to be treated before placing fish in the tank to prevent them from dying due to unnatural purifiers. Soaps and harsh chemicals should not be used to clean your fish tank.
