Yup they are. The amazing thing about them in the wild is that they take a real interest in people. I have found Puffers and groupers tend to like to check people out. Puffers will come quite close. We all know them to be such curious little guys and they are no different in the ocean, especially the young ones.

Although I have found that Dogface Puffers are not quite so bold. They tend to watch you but from behind a rock.

They are probably checking us out to see if we will fit into their mouths. :mrgreen:

GSP, I was just going to say that I came back from travelling around Mexico and Belize and when I was diving off of Puerto Vallarta I saw a school of porcupine puffers. It was quite incredible to see so many of them sticking together. It's amazing to see how differently they behave in the wild compared to an aquarium.

Yeah it is quite amazing!

Its all about space. They don't see each other as a threat in the large open ocean but in tanks they just don't have enough room to share with each other. Same as tangs or angels. The problem is when puffers fight, it gets messy very fast.
