My silver arowana is growing and looking good but he won't eat with me in the room and hides behind my overflow box. He is about 11" and has 2 tank mates a small datnoid and a small peacock bass. He is growing but never comes out and I have had him about 3 months. Any ideas how to get him to come out with the lights on? I would love to show him off but he isn't interested. I have a few small artifical plants driftwood and some rocks nothing at the top for him to hide under. Also I don't think this is a baby thing since he is 11" but that's why I am asking. Thanks for all the help.
