Well my puffer died. Not because he was sick or water conditions, but because there was a deadly flaw with my background. He found a whole just big enough to fit into and got stuck over night. We are so close to getting the tank set up that this really sucks, but we might try and save another one. I have double checked the new background and it seems ok, no real small areas to get stuck. Also got the stand made just need the canopy at this point but that can be put on after the tank is up and going.
