My arowan is 7in and has had ping pong balls in the tank for months now. I have only ever fed him floating food or make him take it from my hand at the surface if it does sink. About 2 weeks ago he ramed the side of the 180g tank really had busting of one of his barbs and a few days later I noticed that the same side that the barb was missing his eye had a slight drop
Since I noticed the eye I have blacked out the sides of the tank except for 3in at the top with black garbage bags and believe it or not I have seen a slight improvement.
I cant leave these in place for ever and was wondering has anyone ever tried that film that you can put on glass that is one way viewing so I can see into the tank but the fish cannot look out and hence down? Also I saw something about using blinking christmas tree lights in the canopy of the tank to keep the aro's attention which should work better than ping pong balls anyone ever tried this?
