You can find the Red Gyarados north of Magohany Town. You find it in the lake. But beware, you will have to find a way to get past that Team Rocket Grunt that you have to pay to get there. I think there is a way on the left but you have to go through grass. OR.....you can pay the grunt and make life much easier but only if you don't care about your money.
It's also possible to catch it. Beat it the same way as a normal Garados..
It is at the Lake of Rage in the middle of the lake. You will have to surf to catch it.
a shiny magi karp will
It is red because it is shiny and its only luck to find one
Easy! Just trade the red gyarados from soulsilver to diamond.
You get the red shard from the red garados if you fail to catch it at the lakeof rage.
a red gyrandos is a shiny Pokemon and it lives with other gyrandos-in water
You get him at the LAKE OF RAGE north of maghony town.

its just a rare Pokemon also its gyarados
it is a red garados (remember shiny Pokemon are rare)
You have to have a action replay ds so you can get weird colored pokemon.
