Siamese fighting fish, or as the scientific name goes the Betta splendens also known as Pla kat in Thailand, are true to their name. How? Well, the bettas are quite aggressive and can fight when kept with other fish. Originally, these fish are tropical beings and can also be found in areas where the water temperature is around 80 F (26.7 C). Over 150 years ago, the bettas were mainly found in the Asian rice paddies and the people there started to keep them as house pets.

Today, a betta can cost around $4-20. The price might increase based on the different types of variants one wishes to buy. It is advised for a pet owner to shift a betta from the fishbowl after a year as the space in a fishbowl might end up becoming smaller and boresome for the fish as time passes by. The betta fish is the only kind of fish that can breathe the air above the water too. This is possible due to the labyrinth organ present in them that helps them breathe air naturally when the water has low oxygen levels. It is important to maintain the waters and keep a check on these low oxygen levels when one has bettas as pets.

Here's a fun fact: Bettas create a bubble nest and the male fish takes care of the eggs as the female betta might end up feeding on its own eggs. Quite interesting facts, aren't they? Check out swai fish and skate fish for more insightful facts about marine life.
