Siamese fighting fish, also known as Betta fish, are often prized for their vibrant colors and aggressive personalities. However, there are several synonyms that can be used to refer to this popular aquarium fish. Some alternatives include the "jewel fish," "fighter fish," "Betta splendens," and "Thai fighting fish." Additionally, in Thai culture, they are often referred to as "pla-kad" or "pla-kat," which translates to "biting fish." While the Siamese fighting fish is a popular choice for aquarium enthusiasts, it's important to note that they do require specific water conditions and dietary needs to thrive.
