Updated 21 October 2026

How to obtain Sulfurous Sludgefish

Target Bubbling Beryl pools on the Coiled Isle. The fish’s use effect reduces enemy detection on Atal’Utek for five minutes, which can help when fishing near hostile creatures.

Where to farm

  • The Coiled Isle

Learn Midnight Fishing and use pool tracking to find fishing activity. Check the pool name before casting when targeting a particular fish. Zone availability does not guarantee that every pool contains this fish.

Keep fish needed by named recipes, fishing quests and lures. For surplus fish, check the selectable inputs in Thalassian Fillet before planning a salvage batch; eligibility differs between catches.

These are reported starting areas, not permanent pools. Vile Venom is useful for Many-Eyed Flounder and accompanying catches; Bubbling Beryl targets Sulfurous Sludgefish. For Willow Sea or Cursed Oddity, continue scouting and check the pool name. The underground Temple requires its own access and is not represented by a surface marker.
