In order to unlock Secret Treasure Under The Great Fish quest, you must first complete the Sidon of the Zora main quest. Then you need to talk to Sidon. He can be found in the throne room of Zora’s Domain. Suppose you can’t teleport to Zora’s Domain. In that case, you can glide there with the help of your Paraglider from Upland Zorana Skyview Tower, the nearest sky tower.

After completing Sidon of the Zora main quest, talk to Sidon to unlock the Secret Treasure Under The Great Fish.
Turn around, and you will see a long bridge. Follow this bridge, and you will see a waterfall below you when you reach the middle.
Jump down to the water and swim to the back side of this waterfall.
Enter the cave entrance behind this waterfall to discover the Cave Under Zora’s Domain.
You will see a hole below you leading down to the Depths. Use your Paraglider to glide to the opposite side to complete Secret Treasure Under The Great Fish quest.
Eventually, you will see another waterfall during your descent. Go behind this waterfall too.
Behind this cascade, you will find yourself inside a chamber with a chest. Open this chest and obtain the Vah Ruta Divine Helm.

Be careful not to wear the Zora Armor Set while completing this mission. This is because if you wear the Zora Armor Set, you will not be able to pass through the waterfall, as it will cause you to move up the cascade. That’s all you need to know about the Secret Treasure Under the Great Fish riddle in Zelda Tears of the Kingdom.
