Why was puffer swimming with curled tail?

I just walked in to one of my GSP's laying on a decoration with its tail curled up. It then swam into the substrate like that and even recoiled away in that same same curled position when I lightly touched it. Then about 10 seconds later it's swimming around the tank completely fine in a normal position. What is going on?

Just did a quick search on this site and it looks like other people's puffers sleep like that. But I also searched the web and it said it can be a sign of stress. Can you guys shed some light on this?

Tank parameters are fine (at least they were - safe start throws off readings so I can't be 100% but I'm very certain), both fish get along well and haven't nipped each other aside from the first 24hrs they were in there, theyre both very active and social, eat ferociously - no other signs of stress whatsoever.

I'm hoping the worst I did was piss off my puffer who was happily sleeping like a cat!

Puffer most certainly do sleep like this. In much larger species a permanent curled caudal fin can be a sign that it was kept in a tank far too small. The only other time I've seen mine clenched outside of sleeping was eight after it was stung by an anemone.
