I have 2 arowana for sale I would really like to sell them as a pair because it is extreamly hard to find two that will get along in a tank they are known to be territorial. one of them will come with a certificate. one is 22 inches and the other is 18 inches very healthy and strong. I believe that the bigger of the two is a female and the smaller one is a male. they have been together for 5yrs. I am asking 450 each, or 800 for both. (i also have a silver for sale he is 14 inches and im asking 150)
