Genshin Impact has many fishes in different shapes, sizes, and species that you can catch. For each, there are different baits and places where you can catch them. Here we will focus on locating and catching Divda Ray & Formalo Ray.
Genshin Impact: Divda Ray & Formalo Ray Location
So where can you catch David Ray and Formalo Ray? The exact location is indicated on the map below in version 2.4.
All you have to do now is throw the bait into the water and when the fish bites, keep it in balance while you are pulling. You will have a bar with marks on how much you will need to pull or keep the balance.
The bait that you will need for Divda Ray is a Fake Fly Bait. It is in a purple color as seen in the image below.
At the same location in version 2.4, you will be able to catch Formalo Ray. Use the same False Fly bait and just repeat the same procedure.
That way you will finally catch both Divda Ray and Formalo Ray!
