Zen stared at the fish on the other side of the glass. The other fish, a slick silver minnow with a scissor tail and a black stripe down it's body, stared back just like it always did. The two of them played this strange little game often, in fact it was the only thing of real purpose to Zen, nothing else in his otherwise lonely life mattered. He swam a little ways up the wall that separated him from his friend, who unsurprisingly followed him exactly. Zen saw that this could be a game of sorts, so he swam further up, then further down, then twirled around to show off his fine fins, his friend mirroring him all the while. After a while zen tired of this little game and bade his friend goodbye, flashing back to the plastic reeds in the corner.
