I was at one of the aquas today or what you guys like to call the lfs, but uh yeah I saw the coolest arowana I thought it was illegal because it was so pink, turns out it is a silver arowana. I wanted that thing so bad. I am still happy with our arowana zeus he is a beaut. Zeus let me pet his back today but he almost tried to bite my finger. I also saw a bunch of arowanas mixed with eachother and other fish in three different aquas. So they can live with others and as long as the fish is a good size the arowana is fine with it, this wont happen all the time though.
