Give the JD some time,they are strange at times,where they like to be left alone or they will go nuts and start going at others for no reason.I currently have a BP with my JD including other fishes and the BP learned real quick not to mess with my JD.Due to the reason the BP claimed the pot decoration for itself and the JD which is a much larger male that is 6 inches,decided he wanted to take that pot over to sit in.So the BP wasn't too happy about that one.
