Control and protect an aquarium filled with fantastic fish and sea creatures by keeping your friendly fish fed and happy… and safe from alien intruders. Collect coins to get better food, new fish and awesome weapons — then use those weapons on the extraterrestrial boss beasts, or you’ll be sunk in an empty tank.
