Bucket of aquatic mob

A bucket of aquatic mob is a form of a water bucket with an aquatic mob (a fish, axolotl, or tadpole) inside.

Obtaining
A bucket of aquatic mob can be obtained by a water bucket on an applicable mob. Once a water bucket is used, the mob is picked up along with the water source block. The mob bucket obtained corresponds to the mob picked up.

Trading
Wandering traders have $1/6$ chance to either sell a bucket of pufferfish or a bucket of tropical fish for 5 emeralds.

Novice-level Fisherman villagers have a 50% chance to sell a bucket of cod for 3 emeralds.

Usage
Pressing with a bucket of aquatic mob places a water source block, and spawns the mob back into the world, leaving an empty bucket in the player's inventory. For buckets of tropical fish, the fish and its details (color, size, name) are kept. Placing a bucket of aquatic mob in the Nether causes the same particles to appear that generate when a normal water bucket is placed in the Nether, and the fish is spawned alone.

Mobs caught in buckets then released do not despawn, unlike mobs that spawn naturally in their aquatic environments.

If a bucket of aquatic mob is inside a dispenser, the dispenser spawns the mob and water block in front of it upon activation, leaving an empty bucket inside. Dispensers cannot pick up mobs with water buckets (the bucket is emptied).

If a bucket of aquatic mob is named a certain name through an anvil, the mob inside display that name as if it were named with a name tag, making fish, axolotls, and tadpoles the only mobs that can exist in item form, and be named without a name tag. Alternatively, if a named mob is captured with a bucket of water, the resulting mob bucket shares a name with the captured mob. If a named mob is captured in Bedrock Edition, the item is called "Bucket of ".

Bucket of tropical fish
Tropical fish also have assigned names that can be seen after capture. In Java Edition, the smaller text under the item name is displayed showing the fish name, similar to the text that displays enchantments under enchanted items. In Bedrock Edition, the item name is displayed showing "Bucket of ". Their colors are mostly named according to the colored block names, though with a few exceptions:



The base color comes first, and if the pattern color is different, it comes after that. Lastly, the fish bucket is given a name according to the shape and pattern of the fish:

Some tropical fish don't follow the normal naming system, and instead, reference real-life fish species. Apart from these names, these types of fish aren't different from regular tropical fish in terms of design or behavior.

These varieties are:

A bucket of tropical fish purchased from a wandering trader or pulled from the Creative inventory spawns random tropical fish when used, due to it having no associated NBT.

Additionaly, buckets of tropical fish may be used to lead and breed axolotls. It can also speed up the growth of a baby axolotl.

Bucket of axolotl
$$, if an axolotl is picked up with a bucket, the bucket appears in the player's inventory as "Bucket of   Axolotl" based on the age and color of the axolotl. These varieties are:


 * Bucket of Baby Leucistic Axolotl
 * Bucket of Adult Leucistic Axolotl
 * Bucket of Baby Brown Axolotl
 * Bucket of Adult Brown Axolotl
 * Bucket of Baby Gold Axolotl
 * Bucket of Adult Gold Axolotl
 * Bucket of Baby Cyan Axolotl
 * Bucket of Adult Cyan Axolotl
 * Bucket of Baby Blue Axolotl
 * Bucket of Adult Blue Axolotl

When the player spawns in an axolotl with a bucket of axolotl from the creative inventory, it is always a leucistic adult. Buckets containing other variants will always spawn that variant when used in creative mode.

The bucket of axolotl does not change textures in the inventory to reflect the captured axolotl's color, it always appears leucistic.

Item data



 * The item's tag tag.

Normal buckets of fish use only the BucketVariantTag tag to store the variant of any tropical fish that is picked up, and the item's display name to store the fish's custom name.

 * See Bedrock Edition level format/Item format.

Trivia

 * When a water bucket is transformed into a bucket of aquatic mob, it actually pushes the bucket texture down one pixel. According to Dinnerbone, JAPPA says this is due to the "weight of the fish".
 * Buckets of tropical fish always appear to contain a clownfish, regardless of whatever fish is actually inside.
 * Since empty buckets can be used to capture fish or axolotls $$, it is possible to create an infinite amount of water source blocks simply by catching a fish mob with a bucket and continually placing and re-capturing the mob.
 * The bucket of cod and bucket of tropical fish are actually re-colorations of each other.
