Caustic Starwyrm is the secret fish introduced in the Brine Storm update. This hidden creature is one of the hardest catches in the game. Finding it is also difficult, as the special requirements to get it are also hard. In this guide, we discuss the location and the easiest way to catch the Caustic Starwyrm in Fisch.
Fisch Caustic Starwyrm Location
The Caustic Starwyrm can be caught inside the Brine Pool of the Desolate Deep pocket area only during a Brine Storm event in Fisch. Use the Fisch GPS and go to these coordinates: X: -1720, Y: -175, Z: -3115, to find the Brine Pool in the Desolate Deep.

The Desolate Brine Pool is a hidden place in the Desolate Deep Pocket. To get there, find the red buoy (Point Nemo) near the Sunstone island on these coordinates: X: -791, Y: 142, Z: -3102. However, the secret fish will not be available right away.
Brine Storm can only trigger during Rain in Fisch and has a 1 percent chance to activate every 30 seconds while rain is active. You can force it by using the Tempest Totem found in a hidden underwater cave near Terrapin Island at X: 36, Y: 135, Z: 1946 coordinates. When the event begins, a notification appears, and the Brine Pool water turns teal, while lure speed and resilience are reduced by half. The Brine Storm lasts for two minutes before the water returns to its normal green color.
Tips and Tricks to Get the Caustic Starwyrm in Fisch

Now that you have all the information on where to find the Caustic Starwyrm, it is time to tell you some tricks to catch it easily. Firstly, you should focus on getting one of the best fishing rods in the game. See our Fisch rods tier list to choose the best among them. Consider going with the Seraphic Rod or Requiem Rod.
- Favorite Bait: Truffle Worm
- Time: Night
- No weather and season preferences
Along with good rods and preferences, you will need some solid enchantments on them to improve the lure speed and resilience. Remember, during the event, catching a fish gets harder with the negative buffs. Moreover, you will need the Invincible enchantment to fish in the Brine Pool if you are not using one that lets you fish there.
