How do I get Mareanie?

Question

I was looking at the pokedex and noticed that the location for Mareanie was unknown so I was wondering if anybody else knew it

Answer 1

To get Mareanie you fish for Corsola in route 9 or Melemele sea, and let it call for help. When it does you have a certain chance (Depending on where you get that Corsola.) that it calls for a Mareanie.

Answer 2

There's a certain fishing spot on route 9 where you can find Mareanie, first you need to find Corsola first, and get wait for it to call for help. If/when it's help arrives, it has a chance of being a Mareanie. I reccomend having a high level Pokemon with false swipe on your team, and net balls or dive balls.
