So, I puted my Siamese fighting fish in the same tank with my goldfish. I read alot of articles and science books about Siamese fighting fish or japanese fighting fish that they dont get along with their own kind, but they get along with other kinds like goldfish. So yeah i put the goldfish and the Siamese fighting fish in the tank. The tank is really big too like 10 gallons. Then i found out and saw my Siamese fighting fish chaisng my gold fishes and like puting their heads and tackling , im not sure if it is tackleing but those fishes and pushing ans stuff. Are they fighting? or playing?
