Where to find Apex Leviathan Fish & Mosslurker Fish in Apex Fish Hunts Event
Apex fish do not spawn under normal conditions. They are exclusive to Apex Fish Hunts, a limited-time event where specific Apex species become available. Make sure the event is active before attempting to catch either Leviathan or Mosslurker. You won’t be able to find them otherwise, no matter how perfect your setup is.
Match the Required Weather, Time, and Location
Each Apex fish has a strict set of environmental conditions you need to meet before it will bite. Here’s a breakdown:
| Fish | Weather | Time | Required Bait | Fishing Location |
|---|---|---|---|---|
| Apex Leviathan | Foggy | Any | Luminous Larva | Open Ocean |
| Mosslurker | Rain | Night | Shark Head | Ocean |
Apex Leviathan only appears in foggy weather, and you’ll need to head out into the open ocean far from shore.
Mosslurker requires both rain and nighttime together, and can be found in the ocean (not quite as far out as Leviathan, but still offshore).
If either the weather or time isn’t right, the fish won’t appear at all — even during the Apex Fish Hunt.
Use the Correct Bait
These creatures are extremely picky. If you’re not using the right bait, you won’t get a bite — simple as that.
Apex Leviathan only responds to Luminous Larva.
Mosslurker will only bite on a Shark Head.
Make sure you’re fully stocked before heading out — these bait types can be hard to find or craft in the middle of a hunt.
Watch for Bite Cues
Unlike normal fish, Apex fish give off distinct signals when they bite:
A light-green exclamation mark appears instead of the usual red.
A unique audio cue plays — deeper and more dramatic than standard bites.
These signals are crucial for recognizing an Apex bite. Stay focused and don’t miss your window — if you fail to hook it in time, it may not come back.
Reel In Carefully
Apex fish are significantly tougher to reel in than regular species. They fight harder, and the reeling process takes longer. Stay calm and don’t try to rush it. If you lose your focus, the fish can escape or break your line.
Ignore the Radar
One of the trickiest parts of hunting Apex fish is that they don’t show up on your radar, even if you’re right above them. You’ll need to rely entirely on matching the correct bait, time, and weather conditions — and hope for a bite.
There are no shortcuts here. Patience and precision are key.
