Many chefs who cook the puffer fish know more than anyone. The puffer fish contains loads of toxic stuff and could kill someone if it wanted to!!

I don't think any do. The puffer fish is extremely poisonous.

it changes every 3 weeks.

His name was Bloat.

yes they do infact i have actually seen that happen

This is not classed as growth as the cells are not getting bigger or developing permanently which is growth. The fish simply inhales water which would only expand the cells temporarily to scare off predators and can easily return to there normal shape

I found the puffer fish in the ocean . they are rare so it took me a long time, but after you catch your first one they come back often.
