Usable items

Pufferfish are passive mobs found in oceans. They defend themselves by dealing damage and inflicting poison to nearby players (if not in Peaceful difficulty) and certain mobs.


In Java Edition, pufferfish spawn in groups of 1-3 in warm, lukewarm and deep lukewarm ocean biomes, subject to fish spawning requirements. If trying to spawn inside a waterlogged solid block, the pufferfish uses the bigger "puffed" size to determine if it collides with anything solid.

In Bedrock Edition, fish spawn underwater at around 12–32 blocks away from the player in groups of 3–5 in warm ocean biomes, and only on the surface; that is, there must not be a spawnable block above the spawn location with a non-solid block on top.


Pufferfish drop 1 of their item form when killed:


Pufferfish inflate themselves when approached by the player, most mobs, ‌[JE only] and armor stands.[1]

The player may collect a fish by using a water bucket on it, giving the player a bucket of pufferfish. Fish placed with buckets do not despawn naturally. When that fish bucket is used against a block, it empties the bucket, placing water with that fish swimming in it. An empty bucket may be used as well.‌[Bedrock Edition only]

Unlike other fish, pufferfish don't swim in schools.


Like other fish, pufferfish cannot survive out of water. Outside of water, they flop around like guardians for a while until they start suffocating, and then die like squid. In Bedrock Edition they rotate when flopping. Fish cannot swim or breathe in cauldron water.[2]

All fish are vulnerable to weapons that have the Impaling enchantment, which also affects squid, turtles, guardians, elder guardians, and dolphins.


A pufferfish inflates when approached by a player in Survival or Adventure mode, a drowned, an axolotl, or any non-water mob within a 5×5×5 volume around the fish, going from unpuffed, then semi-puffed, to fully puffed. Pufferfish are technically passive mobs but going near one when semi-puffed or fully puffed inflicts the player/mob with three or six seconds of Poison based on the inflation level, and touching one in its puffed or semi-puffed form deals damage separate from the poison.

Pufferfish also instantly inflate to their fullest form after taking any kind of damage.‌[Bedrock Edition only] After inflating, they slowly deflate to their normal shape as long as a threat is out of range. If the player/mob leaves the radius while pufferfish is in its semi-puffed stage, it deflates back to normal.

Undead mobs are unaffected by the poison effect, but still take damage when they come into contact with pufferfish.

A pufferfish inflicting damage to a mob other than creeper and ghast via touching provokes that mob to retaliate.

In Peaceful difficulty, pufferfish do not inflict damage or poison to player.

Java Edition Alpha
June 28, 2010Notch mentioned that fish might be a feature of coral, if he were able to add coral: "... I do know that the corals will have tiny fish particles around them."
October 4, 2010Fish were a passive mob that Notch showed interest in adding. In the promotional graphic for the Halloween Update, Notch indicated he would add fish. However, they were added only as an item; there was no code for a fish mob.
Java Edition
October 5, 2012Fish were jokingly teased in the fake snapshot 12marc40awesome, along with coral and "fish blocks".
April 13, 2013When Jon Kågström was asked in his AMA on Reddit, "What mob would you like to implement into the game?" He responded, "I would like to add birds, fish and tree animals to make it more alive. However this will take some time before it can be done."
July 31, 2013During Notch's AMA on Reddit, when asked about what happened to his plans of adding fish as a mob, he responded, "Oh yeah, the fish!"

Issues relating to "Pufferfish" are maintained on the bug tracker. Report issues there.


  • In real life, pufferfish use their spikes for intimidation purposes and not to inject venom. Their flesh is toxic, which is reflected accurately in-game.
  • Pufferfish's damage and poison time is directly related to its current PuffState data value, which can be changed using the /data command.
  • There are three textures for the three different PuffState data values in Minecraft. Exceeding PuffState 2 does not visually increase the pufferfish size, but does create a bigger shadow on the ground. All sizes of pufferfish textures are contained in the same texture file.
