Taillow are found just outside both ends of the Krokka Tunnel (near Fall City and Ringtown). You capture them like any other Pokemon - drawing multiple circles around them. Note that Taillow are weakened by electric blasts from Plusle or Minun.
The first time you can catch Taillow is when Taillow's owner loses it, you can find it in the Lyra Forest, but you cannot find it immediately, first you much catch a Chikorita and Zigzagoon in the area and show it to the owner, he will say that is not his Pokemon and Taillow will roam the forest. Watch out! Taillow is very fast, although didn't put much of a fight for me, circle like mad in the beginning. Note that Taillow can and willrun away after a while.
The second time you have to catch Taillow is when your soon-to-be-partner Pokemon (Plusle or Minun) angered it, your soon-to-be-partner-Pokemon will paralyze it in the beginning so take the advantage! Otherwise its pretty much the same as the other battle, but Taillow will not run away I believe.
no but its spelt gyarados lol
No
You don't
You can catch red Gyarados anywhere because red Gyarados are only shiny but are extremely rare.
train it
In Pokemon Crystal version, you catch it at the Lake of Rage.
To get a red Gyarados in Pokemon LeafGreen you first need to catch a shiny Magikarp. This shiny Magikarp will be able to evolve into a red Gyarados. This is due to the red Gyarados simply being the shiny color of Gyarados.
that Pokemon is not in Pokemon ranger, Pokemon ranger shadows of almia, or Pokemon ranger guardian signs
Catch a shiny magikarp and evolve it.
GYARADOS
A red gyarados is a shiny gyarados (however, the Pokemon Company did not call them shiny untill the Unova Region). You can find it wherever you can find a normal gyarados, but your chances to find it are very slim.
there all over sinnoh just weaken and catch.
