Keep talking to your parrot, repeating the words you want him to learn over and over. It could take a long time or you could be lucky and he will learn in a short time. All birds are different. Try to spend an hour a day total talking to him, or to others near the cage.

do not put your parrot in a fish tank

note: I am pretty sure of this, I'm a parrot owner too.

edit: moving your question out of the pets-fish section to the -bird section for you.....
