RC Flying Fish swim through the air with incredibly smooth and life-like swimming motion. These amazing fish provide hours of remote control indoor fun in even the smallest of rooms (not for outdoor use). They require only four AAA batteries (one in the body, three in the controller) and have complete up, down and 360 degree turning control. The Clownfish and Shark is remote infra-red controlled and will respond to your inputs moving up and down most importantly left to right with fish like tail movement. Remote control has never come to life so magically! The helium filled fish body is made from durable nylon and with appropriate use will stay inflated for weeks depending on altitude.
