This Minecraft tutorial explains the NBT tags (formerly called data tags) that you can use for a silverfish in Minecraft Java Edition (PC/Mac) 1.16, 1.17, 1.18, 1.19 and 1.20.

TIP: If you are not running Minecraft Java Edition (PC/Mac) 1.16/1.17/1.18/1.19/1.20, find NBT tags for silverfish in another version of Minecraft:

  • Java Edition (PC/Mac) 1.14/1.15

Background

In Minecraft Java Edition 1.16, 1.17, 1.18, 1.19 and 1.20, the entity value for a silverfish is silverfish. The silverfish entity has a unique set of NBT tags that can be used in Minecraft commands such as: /summon and /data.

What are NBT tags (formerly called Data Tags)?

NBT tags allow you to set certain properties of an entity (such as silverfish). The NBT tag is always surrounded in {} such as {NoAI:1}. If there is more than one NBT tag used in a game command, the NBT tags are separated by a comma such as {NoAI:1,CustomName:”\”Fred\””}.

NBT Tag Examples

To summon a silverfish that is named Fred:

/summon silverfish ~ ~ ~ {CustomName:"\"Fred\""}

To summon a silverfish that is named Fred and has no artificial intelligence:

/summon silverfish ~ ~ ~ {CustomName:"\"Fred\"", NoAI:1}

Target Selectors

Before we finish discussing data tags, let’s quickly explore how to use the @e target selector. The @e target selector allows you to target entities in your commands. If you use the type=silverfish value, you can target silverfishs:

@e[type=silverfish]

Target Selector Examples

To change the name of the nearest silverfish to Fred:

/data merge entity @e[type=silverfish,limit=1,sort=nearest] {CustomName:"\"Fred\""}

To kill all silverfishs:

/kill @e[type=silverfish]

Next, learn how to use the game commands in Minecraft.
