He is unhappy and possibly feels like the "jar" was a punishment or something. It is going to take a bit to get the rapport back with him and to get him to warm up to the tank again but he will, just give him some time. He has been stressed and maybe could use a treat or two if you know of something he especially likes. Otherwise just get him back to his regular schedule and keep him to a regular schedule and routine as much as possible to show him that everything is going to be the same again and he will be okay.
Please let us know how he is doing.
