Hey, so it is almost the end of the year for some people, so I just wanted to tell all you users I hoped you passed this year and have an amazing summer break! <3

the word that best matches the meaning of the expression "went to the big ocean" is died.

the goldfish died, which is why the father looks at the children mournfully. the "big ocean" is the father's way of saying fish heaven. he could have just said that the goldfish died, but this way, the children imagine the fish in a bigger, better place instead of just picturing a dead fish.

explanation:

it u understand what he thought at the time and let u know more about him then what third person would of known probably. hope this : )
