Brewing Potions with Pufferfish

The primary use for pufferfish in Minecraft is brewing Water Breathing potions. When combined with an Awkward Potion at a brewing stand, pufferfish creates a Water Breathing potion that lasts 3 minutes. You can extend this duration to 8 minutes by adding Redstone dust, making it perfect for underwater exploration and ocean monument raids.

Food Source (But Be Careful!)

While pufferfish can technically be eaten, it’s not recommended for survival. Consuming raw pufferfish inflicts several negative effects: Hunger II for 15 seconds, Nausea II for 15 seconds, and most dangerously, Poison II for 60 seconds. The poison effect can bring your health down to just half a heart, making it extremely risky. However, it does restore 1 hunger point if you’re desperate.

Trading with Fisherman Villagers

Expert-level fisherman villagers will buy pufferfish from you. They typically offer 1-4 emeralds for a single pufferfish, making it one of the more valuable fish for trading. This can be particularly useful if you’ve accumulated many pufferfish through fishing and want to convert them into emeralds for other trades.

How to Obtain Pufferfish

You can get pufferfish through several methods:

  • Fishing: The most common method, with pufferfish being catchable in any body of water
  • Killing pufferfish mobs: Found in lukewarm and warm ocean biomes, they drop 1 pufferfish (or up to 4 with Looting III)
  • Guardian/Elder Guardian drops: Rare drops when killing these ocean monument mobs

Storage and Stacking

Pufferfish stack up to 64 items per slot in your inventory, making them easy to store in large quantities. Since they don’t spoil or have durability, you can keep them indefinitely until you’re ready to use them for brewing or trading.

Whether you’re planning underwater adventures or looking to trade with villagers, pufferfish offer unique utility that makes them worth collecting during your fishing expeditions or ocean exploration in the blocky world of crafting and survival.

TL;DR

Pufferfish in Minecraft are primarily used for brewing Water Breathing potions and can be traded with fisherman villagers for emeralds, though eating them raw causes dangerous poison effects.
