See § Spawning

Items usable on

Pufferfish are mobs found in oceans. They defend themselves by dealing damage and inflicting poison to nearby players and certain mobs, but do not become hostile.


In Java Edition, pufferfish spawn in warm, lukewarm and deep lukewarm ocean biomes in groups of 1-3. In Bedrock Edition, fish spawn underwater at around 12–32 blocks away from the player in groups of 3–5 in warm ocean biomes. Pufferfish spawn only on the surface; that is, there must not be a spawnable block above the spawn location with a non-solid block on top.


Fish 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, 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 fully puffed inflicts the player/mob with seven seconds of Poison, 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. 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 via touching provokes that mob to retaliate.

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!"
