No you have to trade it from Leaf Green or from Fire red
You cant
That's impossible. Cleffa is only obtainable in firered/leafgreen
You must trade from FireRed or LeafGreen
You don't find Cleffa in the wild, but if you get a Clefairy at Mt. Moon and breed it with a Ditto, you will get a Egg that will hatch into a Cleffa. (This is my opinion, but hatching a Egg in Pokémon Silver seems so easy!!) In Pokémon Silver, Cleffa looks so cute!
You can find it: -Mt. Coronet -Trophy garden
in all the caves
Cleffa can be found in Mt. Coronet in the morning at the North and South Entrances.http://bulbapedia.bulbagarden.net/wiki/Mt._CoronetAlso, Cleffa can be found in the trophy garden if Mr. Backlot says so.http://bulbapedia.bulbagarden.net/wiki/Trophy_Garden
