Hi I have one redcap oranda in my small pond (180~ gals). There are 5 other gold fishes (2"-6") in the pond as well. The oranda seems to be always hiding behind a rock. As far as I can tell it is not sick. Every once in a while he comes out and eat at the feeding time. Also at night hecomes out and eats(?) algae and other green stuff hanging from pond wall.
So my question is are the oranda's by nature a bit shy type fish which stays away from other fishes? I have been thinking of getting another oranda to keep it company. But thought I would ask here first
