my porcupine puffer acting weird

[dramsfan]

He has been rubbing up against the rock. Swimming around in real fast bursts. And inhaling and spitting out sand. I have had him 2 weeks and this is the first time he has done this. I did add some fish 2 days ago.

Hard to tell anything without more info. Tank size. Age. Water readings. Especially your ammonia. Total # of fish and what type in the tank. Etc, etc.

Just how many fish did you add 2 days ago?

You added the puffer two weeks ago an then a few more fish two days ago?How many? Were the fish QT? Questions like the age of your tank and your water parameters as mentioned will be helpful as well.
