Fish anywhere with an old rod, catch a magikarp, then get it to level 20.
Evolve Magikarp at lv20, or if you're luck, you can find some at Sootopolis City, use Super Rod.
Go up to Lake Rage and catch the shiny Garydos. Then go through the Rockets Hideout.
Go to lake of rage, defeat or catch a red garydos and you will get a red scale give it to him and you will get a exp share
magikarp
After two days competing in the pokeathlon in the poke dome it was available to me for 1000 points
catch two magikarps, male and female, train them to level 30 each, both of them MUST be at level 30. however DO NOT let them evolve right away. keep them as magikarps, make them have an egg, then the you will have a red/shiny garydos.
in the shop after you catch red garydos go to the shop above the gym that says nothing suspicios here and you will see lance you will figure out the rest
after you defeat red garydos you will receive red scale, take it and go to mister Pokemon who lives alone up from cherrygrove city and he'll give an exp.share
Don't think it does evolve. however it would be cool if it did! I don't use my red garydos in my party anymore as it is just as useless as a normal blue garydos.
