How To Choose The Best 5-Gallon Betta Tank?
One of the most common misconceptions about betta fish is that they can live in a dirty water tank.
The truth is, in nature, they live in shallow water that is a part of a large bio-diverse ecosystem. The water there is, in fact, well-oxygenated and clean thanks to a lot of plants.
Another misconception is that because bettas can take in oxygen from the air, they can live in a small body of water. This ability only helps them jump from puddle to puddle until they reach a water body large enough for them.
Therefore, you need to get a tank filter for them, to ensure the tank is clean and there’s always enough oxygen for them to breathe.
If you don’t buy a tank filter, you have to change 40% of the water every three days.
Bettas originate in Cambodia and Thailand, which means their natural environment is very warm. So, to give them the right condition, maintain the tank temperature higher than 76 degrees F.
Unless you live in a warm climate with the same environmental temperature, you will need a heater.
Plus, you should place a thermometer at the other side of the tank from the heater to ensure the right temperature all over the tank. Ideally, the tank should be between 78 and 80 degrees F.
There are a lot of shapes for you to choose when shopping for a betta fish tank.
Some of the most common choices include traditional tanks, bow front tanks, round bowls, Zen looking tanks, tanks with dividers, etc. You can freely choose whatever shape you like depending on your interest.
If you want to admire the beauty of your Betta fish, LED lighting is the best choice. LED lights are energy-efficient and do a good job of showcasing the fish’ spectacular colors.
Keep in mind that Betta fish need a regular pattern of night and day. Therefore, you should choose a tank that has to daylight and moonlighting to make sure the fish stay healthy while you can watch them day and night.
