My five million pets...

I have four goldfish myself, and they're currently being spoiled in a fifty-five gallon with a super filter because I didn't want to have to relocate them when they get to be ten inches long...
I also have cats, finches, gerbils, sugar gliders, chinchillas, other fish, and a mouse (pictured on that page). I'm getting my USDA licensing ASAP so I can sell the glider and chin babies... I've always wanted to raise baby animals but it took me a while to find something that wasn't overpopulated in my area...
