Seven Seconds of Clownfish

It doesn't know how many fish there are in the fish tank. Because it doesn't count to 7. But it knows that every time it opens its eyes, there are fish around it. Some are bigger than that. Some are smaller than that. Some swim fast. Some swim slowly. They share the same blue, the same fake coral, the same invisible wall. And the same sea anemone—always on the other side of the glass, never out of reach.
