Black shiny mollies and bright colored guppies,
Shy little angels as gentle as puppies,
Swimming and diving with scarcely a swish,
They were just some of my tropical fish.

Then I got mantas that sting in the water,
Deadly piranhas that itch for a slaughter,
Savage male betas that bite with a squish,
Now I have many less tropical fish.

If you think that
Fish are peaceful
That's an empty wish.
Just dump them together
And leave them alone,
And soon you will have -- no fish.
