I've never seen a jar with DE (although apparently they very rarely get it) so I wouldn't worry about that. How big is he? You say 5 months, but how big is that?
Usually little jars are quite timid and could do with some cover. Even if you don't have any though, he'll still grow up big and strong in no time with clean, stable water and good food.
Remember to keep the tank covered as most of our aros die doing what keeps them alive and eating well in nature ... jumping!
Good luck!
