Betta fish are known for their bright colors. They are popular with Americans as pets.
They are often kept alone in a small tank. Male fish are prized for their stronger colors and beautiful fins.
With good care, bettas live three to five years, but some are known to live 10 years.
In the northern parts of the world, winter has arrived, and some people might be wondering what to do with their time now that they are indoors. Keeping a betta fish can be a fun hobby that does not involve going outside. It also does not require too much skill, but you do have to be willing to learn.
But how do you take care of a betta fish?
First, betta fish need a home. A tank that holds at least 11 liters of water is suggested although 19 liters is better. Larger tanks are better because the water needs to be changed less often and provides a healthier environment for the fish.
Second, the tank needs small rocks or sand at the bottom. In the pet fish industry, this is called substrate. A few centimeters at the bottom are all that is needed. Clean the rocks or sand with running water without soap until it runs clear before adding them to the tank.
Third, a filter is needed to purify the water. Many people keep bettas without filters. But the fish should be raised with a filter to stay healthy. Follow the filter’s guidelines and choose a filter that is the right size for the tank.
Fourth, a heater is suggested to keep your fish in good condition. These fish prefer warmer water, usually between 24 and 28 degrees Celsius. Pet stores sell heaters for fish. Choose the right size for your aquarium and follow its guidelines, or instructions, to set it up.
A light and decorations are the final details to set up your tank. A light may not be necessary if the room receives enough natural light. But an electric light might be helpful if you wish to grow plants in the tank. If real plants seem like too much work, plastic plants work as well. You can also find other decorations like rocks, or wood pieces. Just make sure they are safe for fish.
Water quality and temperature
The quality of the water is important to keeping a fish alive and healthy. The filter and heater will do a lot to keep the water safe for the fish, but there are additional steps you should take.
Make sure the water you add to the tank is safe for fish. Tap water can be used. But it usually contains a chlorine-based chemical harmful to fish, so additional steps need to be taken.
Krista Keller is a professor at the University of Illinois at Urbana-Champaign College of Veterinary Medicine. Writing online in 2019, she said, “If tap water is used in the tank, it is recommended to use a dechlorinating product and test for heavy metals.”
Pet stores sell dechlorinating chemicals and they are easy to use. Just follow the instructions on the container. Stores also sell home water testing products. But many fish stores are happy to test your water if you bring in a small amount. They can also provide advice on keeping fish in your area’s water.
Betta fish care
After setting up your tank, there are a few more things to consider. You will need to feed your fish and change its water.
There are many choices for food. There are pellets, frozen whole foods, freeze-dried foods, and live food. Pet stores will carry many of these. Feed your fish once to twice a day. Whatever food you choose, make sure it contains meat or insects because that is what bettas eat in the wild.
It is suggested to change one fourth of your tank's water once every week or two. Remove the old water and add fresh water. Your filter also may require some additional cleaning every month or so.
Male betta fish are kept alone because they are aggressive fish. Another name for bettas is Siamese fighting fish. Males should never be kept with other betta males. If you have a larger tank with other fish, they might live together peacefully. But know that male betta fish often attack other fish and may have to live separately.
Female betta fish can live with other fish peacefully. A group of females can be kept too. Make sure they have a tank that is large enough and a filter designed for the tank’s size.
