Burp a puffer?
 

I was just wondering about my dogface puffer ever since I got him he has puffed up on a regular basis.To go to sleep he puffs up in between two rocks.The last couple days he has twicthed side 2 side a few times and I heard of burping pufferfish.Just wondering if anyone has heard of this.

The burping thing is a last ditch effort to try and get a puffer to expel some air. Unless you are sure he gulped air you do not want to try it, it's is a bitch to do.

I assume this is a recent purchase. It's not unheard of to see a young puffer do this sometimes, especially if it is stressed. Check you water parameters to be on the safe side but it is probably just adjusting to it's new home.

actually I have had him for about a year now.The water is fine he puffs up on a regular basis my freind just told me about it because he thinks he is to big in the belly but he does eat alot so I think he is just tubby
