Everyone needs a helping hand sometimes - or a fin in this goldfish's case. When YouTube user Synirr discovered that his fish friend had some trouble swimming on her own, he created a sling to help her out. Because she had trouble maintaining buoyancy by herself and typically spent the day lying at the bottom of the tank, her owner created an innovative tool to help her swim around with the other fish. How sweet is that? Check out his cool contraption in action.
