The tracker has the new legendary fish added in Patch 7.55, but as always, the exact conditions for catching them are still being discovered. The tracker is manually updated to reflect the latest findings about every night. Remember to use the Fish’cord to coordinate research into the latest fishies! Good luck!
You can use the new “Testing Windows” feature (click the icon in the top left, then click Testing Windows). Paste the condition data from the Fish’cord. To just view the test windows, type [TEST] into the search bar.
