1. Body length difference: The body length of wild Thai fighting fish is only 5 to 6 centimeters. Under the condition of artificial feeding, it can grow up to about 8 centimeters. The adult Chinese fighting fish is between 5 and 10 centimeters long, generally longer than the Thai fighting fish.
2. Body color difference: Thailand fighting fish color is more bright, and fish body exudes metallic luster. The color of Chinese fighting fish is relatively dim, mostly gray-green and brown, which is not as bright as that of Thai fighting fish.
3. Fin Differentiation: It's easy to tell a fish by its fins. The fins of the Thai fighting fish are long and large. In particular, the dorsal, anal and caudal fins are very broad, and the caudal fin is fan-shaped. The fins of the Chinese paradise fish are long and pointed. Its caudal peduncle is very short, and its caudal fin is shaped like scissors.
The Thai fighting fish and the Chinese fighting fish both belong to the fighting fish, and the conditions of their living environment are basically the same. Theoretically, they can be raised together. But they are very aggressive, especially the male betta. If two male fish are raised together, it is very easy to fight. But females don't fight each other. Therefore, if you want to raise two kinds of betta together, you can choose a female and a male or both female fish. But the number should not be too large, otherwise they will also fight.
