How to Care for Your Betta Fish

To care for your betta fish is not difficult. This article proves how.

The most important fact to note is that one cannot keep more than one male Betta in a single bowl or tank - they are known as "Fighting Fish" and it's for some reason. But one male betta can be kept with quite a few female betta fish provided you have enough space. Some believe that these fishes cannot be kept with other kinds of fishes. But this is not true and you can keep one male betta fish and a few female betta fishes even in a community tank. Just make sure that there are no aggressive breeds present.

Your bettas shall be much happier and healthier if attention is paid to the cleanliness of their water. Change at least half of the water once every week or sooner if it starts to turn cloudy. Also make sure that you use aged water for changing, meaning, let it stand for twenty four hours. This shall also help in releasing the chemicals (especially chlorine), if there is any.

These fishes have tiny stomachs. It is therefore recommended that one gives small quantities of food maybe twice a day. All kinds of frozen foods and pellets are available in the market but bettas love live food like worms and brine shrimp and so it is a good idea to treat them with these once in a while.

These fishes like the temperature of the tank to be between 75 and 84 degrees or 24 -30 degrees Celsius. The ph most suited to keeping them healthy is in the range of 6.8 to 7.3.

Bettas tend to jump out of the water, so make sure you have some kind of cover on the bowl or tank. We normally have a few tank accessories or decorations and care should be taken not to use soap while cleaning them. Even a slight trace of soap residue can have an adverse effect on the health of your beautiful fish.

Keeping betas is an interesting, enriching and a very satisfying hobby. Once you start on this, your hobby shall grow and you shall want to keep many more of them and learn all about this amazing species.
