According to Dr. Dean Pomerleau of R2 Fish School, whose fish holds the Guinness World Record for largest repertoire of tricks, almost any fish that is 1-6 inches in length can be trained. This kit contains step by step instructions that teach you how to use food rewards to train fish to perform ridiculous and entertaining feats. Teach a goldfish to play fetch, shoot hoops, swim the slalom, limbo dance, play soccer and more. Includes a 45 minute DVD, special feeding wand, training field, base platform, and more fish training paraphernalia.
