AnvilTropical 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 <fish name>". Their colors are mostly named according to the colored block names, though with a few exceptions:
White
Silver
Gray
Black
Brown
Red
Orange
Yellow
Lime
Green
Teal
Sky
Blue
Plum
Magenta
Rose
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:
Flopper
Glitter
Betty
Stripey
Blockfish
Clayfish
Kob
Snooper
Brinely
SunStreak
Dasher
Spotty
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.
Neutral mobs are sometimes passive and sometimes hostile toward the player. Many neutral mobs become hostile only when attacked first, but other neutral mobs have other ways of being provoked. Some may be naturally hostile with provocation.
↑ abcdeAll nearby mobs of the same type become hostile when a single one is provoked.
↑In addition to attacking when provoked, bees become aggravated when a nearby beehive is broken. Bees who claim a beehive become angry when honey is harvested unless a campfire is placed beneath the beehive. A bee can sting the player only once, and ceases to attack thereafter although the bee's hostile texture remains. In addition, they become passive after a short time.
↑In addition to attacking when provoked, iron golems attack players with low village popularity.
↑This mob becomes neutral after attacking the player a single time.
↑Most panda personalities attack the player once. Aggresive pandas attack more similarly to a hostile mob when provoked.
↑Baby polar bears are passive. When the player is near a cub, the parent polar bear becomes hostile toward the player. When a cub is attacked, nearby polar bears become hostile toward the attacker.
↑ abThis mob is naturally hostile when in a light level 7 or lower; meaning they are naturally hostile whenever they spawn. They become neutral when in a light level higher than 7, although they continue attacking any players they were attacking before being in this light level.
↑In addition to attacking when provoked, endermen become hostile when their head is being looked at.
Hostile mobs[]
Hostile mobs are dangerous, aggressive mobs that always attack the player on sight.
↑ abOnly the riding mob of the pair is hostile. The mount remains passive after its rider is killed.
↑The skeleton variant is always hostile, while the spider follows its normal rules.
Boss mobs[]
Boss mobs are special hostile mobs that are distinctly more dangerous and tougher than other mobs. They do not spawn randomly, and are confronted intentionally. They also have a boss bar featuring their name and health. Boss mobs provide unique challenges but also equivalent rewards.
Unused mobs do not spawn naturally in-game but are functionally in game. They can be spawned only with the /summon command, and the Zombie Horse with the Spawn Egg.
