Red-hearted perch is a kind of fish in Genshin Impact, which is only distributed in Feng Dan. This is a strange fish with a heart-shaped outline. It is said that it is related to perch. Because its dorsal fin and ventral fin are composed of pinnate slender cartilage, it is named "Heart Feather Perch" by scholars. In the water, sea bass has a unique color like sunshine, which is very eye-catching.
