This is absolutely inhuman. Nothing living (except perhaps plants) can happily be contained within. Any fish living in it will live a short life of stress. Please don't do this to your fish. I see a lot of people putting faucets in, not realizing they need at least 2.5-5 gallons to be happy, plus a filter and heater. "Roosters live their whole lives in puddles" is a myth. They can survive in small puddles when the dry season comes, but they cannot stay there all their lives or they will die. For a little more money you can have healthy, happy fish for over 7 years. Please keep this in mind when looking for "cool tanks" for your fish.
