I have a 6 line wrasse, yellow tang, blue tang, Percula clownfish and 2 Azure damsels and apart from the tangs cruising around the tank, all the other fish mostly hide. As soon as I approach the tank, the tangs dive for cover as well. I guess I need some dither fish but has anyone else experienced this where the fish hide most of the time? I purposely created a lot of places for the fish to hide but maybe this was a bad idea! The tank is not in a high traffic area so they are not being scared because of noise or people walking past the tank often. I wonder if I need some more dither fish but when I see other people standing by their tanks, their fish seem to come begging for food whereas mine dive for cover!
