Learn how to get Corrupted Fish in Blox Fruits during the Oni Realm event and use them for crafting powerful event items.

The Oni Realm event in Blox Fruits adds new resources, and one of the most important is the Corrupted Fish. Unlike normal fish, you can only catch these corrupted ones inside the Oni Realm, and they are required for crafting event-exclusive gear like the Shark Corrupted Rod. Since they only drop during whirlpool fishing, players often struggle to collect enough before the event ends.
In this guide, we will tell you how to reel in Corrupted Fish, the requirements, and the best way to maximize your farming before the event ends.
What is Corrupted Fish in Blox Fruits?

Requirements Before Fishing
