I know I have had him only 3 days, but the poor little chap seems to be really stressed still. He is eating fine and swims up and down the tank like a loony. Yesterday he lost most of his black banding, but its all back again today
If I go near the tank he shoots under the filter and hides. In the shop he was in with another gold JD that was a real bully (when I actually went back to the shop the one I picked was lying on his side on the surface hiding from the other one). He has plastic plants and the filter to hide under, just wondering how else I can make him feel more comfortable
