Betta splendens aquarium fish differ from the savage fish found in the natural
biotrop. They are part of the Anabantidae species that are characterised through the existence of
an additional respirator organ.
These fish are found in warm sloughs with little oxygen and originate from South
As these fish have very few demands, they can live in a small aquarium sometimes
with no airing at all.
For this reason it is recommended that they be kept in small aquariums, even
jars so that they can develop properly and take on their best natural shape.
Being kept in small spaces it is important to regularly change their water. These fish don’t
really care about the type of water used (the roughness and pH) they only require a constant temperature that is
28-30° C and for propagation purposes to increase water’s temperature by 1-2° C.
If you keep your Betta fish in a 1 liter jar you will need to change their water every second
day ensuring that the temperature of the old water and the new are equal.
If you use tap water it is preferable that it should be at least 24 hours old, even for a
non-demanding fish, huge differences in water quality can damage them.
If you notice that your Betta fish are spending more time on the bottom of the tank and their
activity has decreased, it is an indication for you to change their water. By immediately changing their water you
can easily observe an increasing in their activity. It is recommended that you add one spoon of rough salt to every
gallon of water used.
Betta fish are not picky when it comes to food either, as long as their food is given at regular
intervals and in enough quantity there won’t be any problems. You should feed your fish several times a day instead
of just once and you should give them an appropriate amount of food. If you overfeed them, the food remains can
contaminate the water.
Normally these fish live 1 ½ -2 years but there are testimonies where some of them live over 3
years. In order of this to happen you need to be careful with their feeding systems and also very important to
maintain the waters temperature, Betta fish can not survive a temperature under 21° C and over 30° C.
Betta Fish Reproduction:
Betta fish are not picky when it comes to the water quality or their space, but when it comes to
laying eggs they can be picky about the container used. In the Orient they use ceramic and sometimes enameled bowls
for egg laying. The container mustn’t be too small or too big for the fish to get lost in it.
The perfect temperature for reproduction is between 24-28° C, these temperatures reflect their
natural biotope. If the temperature is above this, the fish eggs will be forced to develop faster than normal and
the little fish become weakened and end up dying before they have had a chance to learn to swim.
