There are 21 unique fish that are part of the Gloomy Crevice Bestiary. Most of these fish are available to catch in most instances, except the Monstrous Cusk that only spawns during its hunt, which players can track using the Global Event chat box.
After exploring the Outer Deep, the area everyone ventures into is the Gloomy Crevice. This is the deepest part of this area and has several unique fishes ranging from eels to some of the scariest anglerfishes. So, if you want to catch all of these fishes swimming around the Gloomy Crevice, here is a perfect guide for you to follow.
How to reach Gloomy Crevice in Fisch

You can reach the Gloomy Crevice by diving further down in front of the Nereus (Main Quest ) building. Otherwise, equip your GPS and travel straight to GPS (-14, -2461, -11733) to find the location.
How to fish inside the Gloomy Crevice
Like other locations, you have to rely a lot on your Harpoon Guns to fish inside the Gloomy Crevice. If you are diving directly from the surface to the Gloomy Crevice, you should definitely try to get some Harpoon Guns like Relic Piercer, Trident Striker, or the Crystal Crasher to make your life easy over here. I suggest using our Harpoon Guide to get each of the Harpoon Guns in Fisch.

The Monstrous Cusk is not always available to catch inside the Gloomy Crevice and only spawns for a select duration, being a Hunt type fish. You can follow the global Event channel to know if a Monstrous Cusk Hunt is present inside the game or not. If available, go straight to Gloomy Crevice to find the creature swimming around the area. Use your Harpoon Gun and shoot at the head of the creature to deal damage. After a few hits, it will go from the Gloomy Crevice to the Depths main POI. Keep following it and keep shooting at its head until you trigger the Harpoon Gun mini-game with a -90% Progress Speed.
