[GreenSpottedPuffer]

And now we get into the anthropomorphism...lets just enjoy the pics I guess. Hope he stops his monthly puffing for you soon though.

EDIT: i read that again and it sounds bad. I don't mean it in a negative way but sometimes we have to separate what we feel and what is fact. Its easy to get attached to fish and make yourself believe they have feelings and personality when in fact they have behavioral instincts. It does vary a bit from individual fish to fish (of the same species) but not much. Most all puffers act the same and are thought to have 'loads of personaility' which in fact is just how they are. Even in the wild I was able to pet them. They paced in the wild too up and down, up and down the poles at piers...but we like to think they are bored if they do this.

Fish like Puffers have defense mechanisms for a reason and use them for the most part involuntarily. Its not like they choose to do stretch or make sure they can. Its stress.

Anyways, I really apologize for being a bit off topic but the fact is that its not good for them to puff and we want our fish to live long. Just don't want people to read this and think they are doing it for 'fun'.
