my puffer talks to me all the time. ive stopped feeling weird about answering out loud. if hes dead center at the top of the tank hes begging for food "gimme a snack plz" and if hes pacing the back right corner that means "clean my tank NOW NOW NOW!!!!" the best thoughy is when hes napping. he hides under a small shelf under his rock and grays out to snooze. but if i peak in at him, he will roll an eye towards me as if to say "what the #@$%! do you want?! im sleeping!"
