Many variables must be taken into consideration when choosing tank Betta fish. Tank size and shape can have a major impact on your fish. Pet stores keep these fish in a bowl to save space, but it's definitely not an ideal reservoir, if you want your pet to live a long and happy life.
You will need a tank that is 2.5 - 10 liters for your fish so they can swim around freely. ten gallons tank obviously costs more, and takes up more space. However, it does not require water changes as often and your fish will be happier with the extra space.
the shape of your tank is also important. Tall skinny tank can look nice and save space on the floor. However, short wide tank is more suited for a Betta fish, because they are native to the shallow rice paddies of Thailand. They do not like to swim away from the surface. This is because they are capable of breathing air from the atmosphere.
material your tank is made of can have major long-term effect on your enjoyment of your new pet. Plastic containers are the cheapest, but they are easily scratched and can fade and sag over time. For these reasons, it is usually best to glass or acrylic tank. Glass tanks are less expensive than acrylic tanks, and they have several advantages over them as well. They are more resistant to scratches and will not fade. However, glass tanks are a little harder than acrylic tanks. They are also more prone to cracking and provide less insulation than acrylic tanks. You'll need to take advantage of each type of material to consider when choosing a betta fish tank.
