Big fat fish

The poem is about a fish.

The fish swam away
it wanted to play
It swam with its other fish friends
and it went fast
It looks like they were racing
Then they stopped at another part
The lady was taking pictures of him

The fish was white
They had a fight
One ran away
The other stayed

He had a brother
It looked like the same one
It had some black
I knew it couldn't be the same
I looked at another big white one
and said I bet they're both brothers
