Not being allowed to have a real pet in confined space, I began looking into a 10gallon tank to have tropical fish. But the price to get everything started, the rocks, filters, nets, plants, heater, thermometer, I was already spending more money on supplies for fish than books. So i settled for this inexpensive box expecting it to fail. Rocky (who was named so due to his surviving 2 full days in nothing more than a damp broken cup when I rescued him) is now thriving. He loves using the plants I got him as a hammock. Hiding underneath the overlapping leaves resting. And now that I'm back home and had the option to put him in a bigger tank, He didn't take well to it and back in his home he went. 2 years later, he's still going strong.
