Natural Habitats of Beta Fish

The natural habitats of betta fish are swamps with dense vegetation and very slow flowing or completely stagnant waters. They do not need to have plenty of oxygen to continue their lives, and they even have the opportunity to avoid larger fish thanks to this feature they have. Because this species prefers to live in shallower and relatively polluted places, other aquatic predators avoid living in such areas. In addition, the dense vegetation in the habitats of bettas prevents them from becoming a clear target for reptiles or birds.

Beta fish do not need oxygen like other fish, and they owe this to evolution. Because over millions of years, they have survived in places far from other species and adapted to this in order to continue their species.

Unlike other fish, beta fish have another respiratory organ, called a labyrinth, that allows them to survive even in places where the amount of oxygen is very low. This additional respiratory organ ensures that the free oxygen in the air is used for respiration. Beta fish can survive in conditions that most other aquarium fish cannot survive, thanks to the respiratory system they have developed.

beta fish , It should be kept alone in the aquarium. Regardless of whether they can survive even in the absence of oxygen, they should be present in at least 20 – 30 liters of water in large aquariums. Although they may live longer in far fewer, it should not be forgotten that it is just as important for them to enjoy life and feel healthier. In fact, beta fish, if they are worried and stressed, throw themselves out of the aquarium they live in and commit suicide. Therefore, the living conditions provided to them must be suitable for this species.

Bettas are aggressive fish, as mentioned earlier, they should live alone. While they tend to fight with other fish in the same environment, if they stay in the same environment with a fish of their own kind, they will definitely fight. For this, it is enough to show the beta fish by holding a mirror and observe how it reacts. But while doing this, you should not miss the dose. Since this fight will stress the betas, it can also negatively affect their health.

On the other hand, this mirror experiment is a good exercise for the fitness of betas “provided it is never prolonged”. Because this short-term moment of danger contributes to their being physically vigorous and alert. And of course, since they open their fins completely at this time, they also offer a visual feast to their owners.

Fights are sometimes organized for beta fish, which are notorious for their aggression. This is extremely wrong. Beyond being ethically wrong, if the beta fish left in such a situation get into a fight, they will surely continue until someone dies.

The best water for aquariums is rested water. But if it was bought recently and the water did not have a chance to rest, the aquarium should be filled with drinking water. Because tap water contains very high levels of heavy metals and chlorine. This can cause your betta fish to die in the long run.

While their water is being changed, an entirely new water may do more harm than good to them. Therefore, less than half of the aquarium water should be changed every 2-3 days.
