Pufferfish is mainly used for brewing a potion of water breathing but it can also be used for taming nautiluses trading with villagers healing wolves and feeding dolphins. In this guide we will go through all the things you can do using this fish.

All Pufferfish Uses in Minecraft
Pufferfish may seem like a rather useless fish but it actually has many practical uses.
Brewing Potion of Water Breathing
The first and most important use of pufferfish is brewing a potion of water breathing which allows you to breathe underwater for a certain amount of time. It is one of the most useful potions during exploration of oceans shipwrecks and ocean monuments because it removes the need to constantly surface for air. You just need to place an awkward potion in a brewing stand and add a pufferfish and after some time you will get this potion.

Feeding Dolphins
If you feed a dolphin a fish including pufferfish it will start leading you to the nearest underwater structures such as a shipwreck or underwater ruin. This is very useful during ocean exploration because instead of searching randomly you can quickly find locations with valuable loot. The dolphin will swim in the direction of the structure and you just need to follow it. Thanks to this you can speed up finding chests and rare items.
Trading with Villagers
Fisherman villagers can trade with you and offer emeralds in exchange for pufferfish. At one of the trade levels you can sell 4 pufferfish for 1 emerald which is a fairly simple way to earn this currency.
Healing Wolves
Another practical use is healing wolves. If you feed your injured wolf a pufferfish it will restore 2 health points which is one heart. Thanks to this you can quickly bring your pet back to full health after a fight.
Taming Nautiluses
Another practical use is taming nautiluses. You just need to feed a nautilus using pufferfish or a bucket of pufferfish and after a few attempts it will become tamed. Thanks to this you will be able to move faster underwater and gain an underwater mount.
FAQ
Can You Eat Pufferfish in Minecraft?
Yes pufferfish can be used as a food source but it is definitely not a good idea. After eating it you will restore a small amount of hunger but you will also receive strong negative effects such as poison hunger and nausea which make movement and hunger regeneration more difficult for a short time.
Does Pufferfish Kill Other Fish in Minecraft?
Pufferfish does not actively try to kill other fish in Minecraft because it is not an aggressive mob and does not hunt other creatures. However it can deal damage when it inflates and other mobs get too close. This means other fish can be accidentally hurt.
Where Are Pufferfish in Minecraft?
Pufferfish spawn in warm ocean biomes such as:
- Lukewarm Ocean
- Deep Lukewarm Ocean
- Warm Ocean
You will most often find them swimming in the water on their own. They are relatively easy to find if you spend some time in the right biomes.
