The Sea Leviathan in Fisch is one of the many exotic fish added to Second Sea, and it’s extremely difficult to get because it doesn’t show up in your in-game announcements like other exotic fish, making it harder to catch in the waters.

Roblox’s Fisch just received a major Cursed Seas update, and it is filled with new bestiaries containing new fish for players. While you can easily obtain some in different islands, others like the Sea Leviathan require you to get some conditions right to have a small chance at getting the fish in your inventory. If you’re struggling to add the Sea Leviathan to your bestiary, we’ve got you covered with this guide.
