You're not the only new explorer of the updated oceans, mind. We've filled the seas with new types of fish! Above is the delightful pufferfish, which filled me with delightful poison because I was too busy taking that screenshot to swim away in time :(

Pufferfish are uncommon defensive mobs found in oceans.


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 only spawn on the surface (i.e., 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, and armor stands.[2]

The player may collect a fish by using a water bucket on it, giving the player a bucket of fish. 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.[3]

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,‌[Java Edition only] or instantly to the fully-puffed state.‌[Bedrock Edition only] 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.

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!"
