I de-chlorinate all of my pets water but I've only had him for a day and I'm not sure if the pet store does. Plus, he started this before he even made it home to my water. It definitely feels like air. He's moving around and is very alert and responsive but it's obvious by the way he moves that something isn't right. I'm going to google it now but you could probably give me a more informed answer as to the differences in hard and soft bloat. I know in dogs it's an intestinal/stomach thing but I don't know much about bloat in amphibians.
