He's Alive!!!
Hi, Pufferpunk. My puffer didn't die
I submerged him in water and after 5 minutes or so - I came back and he was swimming at the bottom of the bucket. I thought he was dead because I read somewhere that once a puffer inflates out of water - there's no way for him to deflate.
I removed him because he wasn't looking very well - swimming at the surface and moving kind of crooked. So I conditioned a fresh bucket of water intending to place him in it temporarily until I could figure out what was the matter with the tank. That's when he inflated.
When he deflated - he was swiming and acting like normal in the bucket. So I did a 75% water change in his tank and put him back in it this morning. He seems to be 100% back to normal now - relaxing at the bottom of the tank in his cave.
I will monitor him for the rest of the day, but I think that everything is OK now.
Thanks for your help and support. Tinister
