And in case you didn't catch it, Fishy is a banded kokopu, Galaxias fasciatus, a galaxiid of the genus Galaxias. Fortunately for Fishy, when he was a tiddler - a whitebait - he didn't end up in a whitebait patty at the local fish & chip shop (hope the kiddies weren't traumatised by the thought). End of learning moment.
If Kiwi kids absorbed this sort of knowledge at a tender age through children's TV programming, how come the country isn't turning out a generation of Einsteins yet?
Damn, can't get that Fishy song outta my head!
