My friend went to the LFS and saw these two silver arowana last night for $22.99. It was the best deal. I couldn't pass it up. So I told him to buy it and will pay him later. One aro was 5 inch and the other is 6 inch. I have them in a 40breeder tank for now. Should I keep them separated? They were both at the store in the same tank. They seem not to fight. They both look different. I might have a pair.
