My Pet Fish

I have two pet fish, Thea and Freckles...
They're over two years old.
You'd think by now I'd be used to them,
Not doing as they told.
I ask them to be quiet,
When I'm trying to sleep.
But the continue moving stones.
Like they never heard a peep.
Sometimes they'll blow bubbles...
Right up at the edge of the top.
I can hear them doing it all night long.
Getting tired as they pop.
So please can you be quiet. I just really need to sleep.
I promise that tomorrow!
They'll be a reward that you can keep.
