The Lost Isle is an endgame location in Fish It where players can reel multiple Secret-rarity fish, including the Giant Squid, Robot Kraken, and King Crab. This is an underwater area with two sub-locations, namely the Sisyphus Statue and the Treasure Room, and you must have Diving Gear to access both. Players can purchase this equipment with 75,000 Coins from the Utility Store on Fisherman Island or acquire it as a gift from a friend.
This guide tells you how to access the Lost Isle in Fish It and features the entire Treasure Room and Sisyphus Statue index.
Where is the Lost Isle in Fish It?

The Lost Isle is in a remote corner of the Fish It world. Spawn a boat on the Fisherman Island dock, head to the northern edge of the map, and you’ll eventually find a marker with the location’s name. Keep sailing to find a small island that consists of a Diving Gear next to a seat.
After equipping the Diving Gear, dive underwater to explore the Sisyphus Statue and Treasure Room sub-locations. These are also the areas where you can fish to complete the Deep Sea Quest and acquire the Ghostfinn Rod.
All fish in the Sisyphus Statue

The large temple that players see underwater is the Sisyphus Statue sub-location. After diving, swim past the waterfall that looks like a door and begin fishing to collect the following aquatics:
Given that the pool in Sisyphus Statue contains multiple Secret fish, prioritize getting a fishing rod and bait with high Luck before accessing this area. The Angler, Ares, and Bamboo Rod, with the Singularity Bait equipped, are ideal for AFK-farming the Secrets.
All fish in the Treasure Room

The Treasure Room is the deepest area in the Lost Isle. To access it, swim into the massive chasm till you find a waterfall-like doorway. You’ll enter the Treasure Hall by going past the doorway, and this leads to the Treasure Room.
The pool in the Treasure Room has fewer fish than Sisyphus Statue. Still, you can catch the Queen Crab and King Crab from the pool.
While catching fish, use the Weather Machine to activate different events that increase the fish mutation chance, a rod’s reel speed, and more.
Angler Rod location in Fish It

While underwater in the Lost Isle, you’ll notice a smaller temple close to the larger one that leads to Sisyphus Statue. This mini temple contains the Angler Rod, which any player can purchase with 8,000,000 Coins.
