The Puffer Forum

The LFS that has helped us set up the tank from the beginning said no water changes until at least 12 weeks because it will mess up with building the healthy bacteria. But this poor puffer looks so sad, I guess it's worth a shot.

We have about 40 pounds of live Fiji rock and 40 pounds of dead rock.
I'm assuming by source water you mean what I add to the tank?
It's water that I bought from the pet store and didn't test it.

I just got a porcupine puffer today, about 4 hours ago. When I first put him in, he swam around for about 16 minutes or so and seemed to be ok. Then he went behind a rock and laid down on the sand and has barely moved. He almost looks like he's gasping for air. Tank specifics are this: Nitrite 5 Nit...
