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.They both have a VERY good appetite I currently have them eating shrimp and feeder fish. I am asking 300 each, or 500 for both.
