I already had a 20"+ Silver and he became scared to death of me for some unknown reason so I kind of don't want another Silver because of that unless it is just a rare thing for that to happen. That was my first Arrowana. I am thinking about a Black Arrowana. I would love to get a Jardini but I know that wouldn't work for too long. Any suggestions? Are Lechardti's calmer than Jardini's?
