After being up since yesterday and thankfully able to talk to all of you, may I first say my very appreciative thanks for your help and care. I have learned so much about Puffers in the last 48 hours.

We now have a 29 Gallon Eclipse w/ an Eclipse 3 lighting and filtration system. We got the Instant Ocean salt, thermometer, heater, master testing kit, salinity checker, few little books, all for $229.99.
We left the old filter on top of the new one to help the system; we used 20 gallons worth of Bio-Spira. Of course before that we checked all of the water; we used Prime to clean it all out and let it sit for a bit while we got the tank setup.
We are using crushed coral sand for now, we were unable to found the Aragonite and Petco said they'd have some in stock soon.
The temp is being stabilized at 80F.
The salinity is 1.014 (as it has always been).
The nitrate is up from 0 at this point, at 20.
The nitrite is at absolute 0.
Water is very hard.
For the alkalinity its 300, showing in the ideal range.
And the PH level 7.8 or 8.4.
The ammonia level is at 0. (Yay ideal!!)
We're going to use the master kit later on, and found a very nice shop who said to take a sample of our water in just in case tomorrow. As you can probably guess we're very tired. We had to run an hour away to get a lot of the materials, and for the Bio-Spira we had to go 30 minutes away, thankfully we kept it cold. We rushed home as we didn't want to leave him along for too long.
And those dark stress spots, completely gone!!!
Here is a picture of his new tank:
And another picture of him:
BTW Mr. Fishy is acting much more normal now; I'm going to try and feed him some of his brine shrimp in a little bit; he seems to be really loving the new tank and he's swimming all over the place. He's back to his normal staring contest with me.
Again, I'd like to say thank you to all of you. If it weren't for the wonderful information and help, I don't know what we would have done. I'm going to stay on these forums and participate much as possible, as I'd like to learn much more about these cute, personable puffers. I fully believe he'll be back to good now; we will keep checking the water on a daily basis, and I'll be keeping in touch with all of you.
I believe he is a GSP, from looking at other GSP's today, he looks pretty much the same. I was told numerous times today that it's incredible he's lived this long in a 5 gallon tank, and that makes me happy because I absolutely love my Mr. Fishie.
