I need an ID on a sick puffer, so that I can do what's appropriate for this species of puffer. Secondly, I need some help on relieving whatever ails it.
First, please confirm that this is, in fact, a specimen of Tetraodon fluviatilis. You cannot tell from the pictures, but the eyes are blue. It's about 4.5"-5" long.


Now, as to the "sickness:"
Details:
-it's "panting" heavily at the bottom in one corner of the tank
-new (to me) puffer: have only had it for 2-3 days
-was fine on first day, crushing whole 0.75" snails
-added salt to 1.004 - I used
-I now know that this was too sudden
-would that have killed all the bacteria that's needed in cycled aquarium in the 1-2 days since I added the salt?
-if so, does that mean that my puffer is now in the equivalent of a non-cycled aquarium? (<-- important question)
-added ammonia neutralizer - this might be bad, too!
-why is he "breathing" at the bottom like that?
-could space/room in the tank be a factor? he's in a 36" x 12" x 12" right now - only temporary for two weeks (is this too long?) - approx. 22 gallons.
-I've lowered the SG to 1.002 - should I put it back down to 1.000? Is all the bacteria dead, so either way I'm dealing with an uncycled tank?
-what do I do? please help!

Postscript: How do I post images in-line (in the message)?
