Sometimes when I walk by my puffs tank he goes by one of his filters and puffs up. I finally had a camera ready and were able to snap a few pictures, I don't think there is anything stressing him into puff, and he always depuffs afterward and swims away. I don't do anything to scare or stress him into puffing and would never suggest anyone to do it.
