The Betta tropical fish has become very popular with tropical fish keepers all over the world as an attractive aquarium fish as in the past it was mainly kept by enthusiasts in Thailand. They come in a variety of colors from red, blue, black and yellow and are stocked in most good pet stores. Keeping Betta tropical fish is really not difficult and just needs some determination and enthusiasm.
It is the male Betta fish that has the long feathery fins and enjoys strutting his stuff but he can be quite aggressive at times. The females on the other hand have shorter fins and do not have such bright prominent colors. Bettas fish also have a special organ, the lanyrinth, that transforms the water molecules into oxygen and therefore need to be able to reach the surface of the water easily.
As with all fish in the wild the Betta tropical fish is predatory and hunts for smaller creatures like insect larvae and small shrimps in amongst the submerged undergrowth of the warm waters of South East Asia. Therefore, it’s important that fish bred in captivity are kept in habitat similar to their natural environment and the aquarium should provide a slow water current and plenty of aquatic plants for shade and hiding places.
The Betta fish needs to be kept in warm temperatures so it’s important that the water in the tanks be maintained at between 75 to 86 degrees Fahrenheit with acidity around 6.5 pH. To keep them in good condition they should be fed on a diet mainly comprising protein flakes, brine shrimps and worms etc. It is not uncommon for them to grow to around 3inches in length and if kept in good health can live up to three years.
Although the Betta fish has an aggressive streak they can get on with other tropical fish. However, it’s not advisable to keep them with other aggressive species. The male Bettas can be kept in the same aquarium but only if they are well-maintained because there is a high chance that they will fight and injure or even kill each other.
When it comes to reproduction, the Betta tropical fish procreates in an unusual way. The male will create many bubbles at the surface and create a floating bubble nest. He will then try to woo the female by displaying his elaborate and colourful fins which will be very vivid at this time.
If the male managed to attract a female that is ready to reproduce her colors will also have changed and she will develop dark stripes and her bloated belly will be full of eggs. Unfortunately, this brief courtship can be hazardous as it involves some chasing and aggression which can result in some small injuries. When they are ready they will swim in the nest of bubbles and start to entangle their bodies and this action encourages the female to release her eggs so that they can be fertilized by the male. With a bit of luck these will then develop into a new generation of Betta fish.
