Well I have my 2 medium size angels and a common plec in my new 55 gallon tank. I just bought 6 golden barbs since they get 3 inches and i wanted a schooling fish. The angels are leaving them alone and everything but when it comes to feeding time... they are always on the bottom of the tank. I have had them in there for a good 24 hours and they swim around and stuff even comming up to the middle and top for a few seconds but right when i open my lid they bolt down and hide under my slate tunnel and the angels gobble up the food. How should I go about feeding these guys? Will they figure it out eventually or what?
