Rusty Koi & Golden Koi in Genshin Impact: Fishing location and best bait details

Rusty Koi and Golden Koi share four fishing locations in Genshin Impact, and both require Fake Fly Bait. Players will want to catch these fish to obtain The Catch polearm from the Fishing Association in Inazuma.

The only difference between Rusty Koi and Golden Koi's fishing locations is one single site. While Rusty Koi spawns in Cider Lake, the Golden Koi appears in the Stormbearer Mountains. Otherwise, the two fish spawn together at the other four locations in Genshin Impact.

Fishing locations for Rusty Koi and Golden Koi in Genshin Impact: Bait details and more

The interactive map showcases all the fishing locations for Golden Koi and Rusty Koi. If the locations are hard to see, zoom out. The fish icons stay the same size no matter what, which makes it easier to locate them. Afterward, zoom in on the appropriate location.

As Genshin Impact players can see, these fish share four locations. The only difference lies in their Mondstadt spawn. Both share three fishing locations in Liyue, with the last one situated in Inazuma.

Twenty Golden Koi and 20 Rusty Koi are required for players to acquire The Catch. Considering both fish can appear at any time of the day, players don't have to skip time to find them.

However, they should note that some locations may spawn other fish, so they might not see Golden Koi or Rusty Koi immediately.
