After completing LeafGreen I started up my FireRed cart the other day & my Charmander is a Shiny one - I've heard this is pretty rare and also, not to let it evolve as it will most likely return to normal when it becomes Charmeleon.

Is this correct?

I've only ever had one Shiny Pokemon (a Rhyhorn I caught in Silver) so I don't entirely know what to do with it, does it learn different moves?

Thankyooooou.
