Fish, anyone?

So, my lovely sister, in her infinite wisdom, decided to buy Connor two goldfish on Friday while she was babysitting him. I left, we had a cat. I came home, we had a cat and two gold fish.
For those of you who don't know, we tried the fish thing last year. I got Connor a Beta fish. We named him Sid Fishious. And the darn thing lived just long enough for me to get attached to him. Then one morning I found him floating in the top of the tank. He'd turned completely white and was dead as a door nail. So he had the traditional burial at sea. Connor didn't ask much about him after that, thank goodness, because a 2 year old just doesn't quite understand death no matter how you try to explain it.

The last thing I wanted was another fish, let alone two. But here they are, Vern and Shirley. While I have somewhat gotten over my initial irritation at my sister buying them without even asking me first, I am not over the fact that these darn fish are the dirtiest animals I have ever owned! They poop SO MUCH that I have had to change the water in my filtered tank 3 times since Saturday. THREE TIMES! GAH! Does anyone know if they make diapers for fish?
