Hello guys, Im going to buy my first arowana. He is a Highback golden arowana and about 6 inches long. He is from Qian Hu farm cetified. I'm feeling loved @ him. But the problem is his barbles are not equal. one is short. other is long. However in the qian hu arowana web page, they noted that the arowanas barbles should be equal, under arowana buying guide. Please Advice me.
