What you have to know about Bettas
The siamese fighting fish, Betta splendens, is probably the most famous betta representative. Because of its magnificent color and ostentatious shape of the fins enjoying unabated popularity, but unfortunately, often spontaneous purchases are made that mostly every time end up with species-inappropriate husbandry what is more than unfair to the fish.
English name: Siamese Fighting Fish
Group: Labyrinth Fish
Distribution: Asia / Thailand, Vietnam, Cambodia and Laos
Males of the cultivated form (siamese fighting fish) have much larger fins and more vibrant colors.
Males can be kept together in an aquarium in no case. No matter how big the aquarium is. Males always meet and fight each other. The fins are usually crushed and in many cases fights only end if a rival is dead. Female, however, can be kept together according to the space offered by the aquarium.
Bettas theoretically can be put into a community aquarium. But offering a betta male a tank for himself is preferable because Bettas are individualists. Small aquarium should work fine. A betta needs warmth. That is why the future aquarium should be equipped with a heater that gets the water to 75 – 86 °F. An aquarium with dense plantation reaching to even under the surface of the water makes a Betta feel comfortable. A cover of swimming plants also contributes to his well-being. As a substrate dark gravel should be used because it doesn´t reflect the light. Otherwise stress reactions would occur. Bettas don´t like stream. So this should be avoided by using adjustable internal filters.
The male builds a bubble nest on the surface of the water. The optimal water level during breeding is about 6 inches. Water filtration and aeration must be switched off to prevent the nest from being destroyed. The first young fish hatch out after about 24 hours and can receive powdered fish food as the first food. Parents should be removed at this time. The female shortly after donating oocytes and the male after larvae have hatched (24 hours).
