Review on Saim Air Action Diver Aquarium Ornament - Rose Red: Enhance Your Tank with Dynamic Live-Action Movement by Anthony Gutierrez

My 4 year old son won a goldfish at the county fair two months ago and I've been campaigning to keep this goldfish alive ever since. We love this decoration! I didn't even realize it until we caught him with a treasure chest. As others have pointed out, it's fairly weightless, so it won't sink if you just toss it in your tank. We have a 20 gallon aquarium with lots of gravel so keeping it in the gravel wasn't a problem. It's easy to connect to the air pump and it's off and bubbling. Good value for money!
