After mining infested blocks or from spawners in strongholds.

Silverfish are small, bug-like hostile mobs found in strongholds, igloo basements, and mountains.


Silverfish have no drops other than 5 when killed by a player or tamed wolf.


Infested blocks[edit]

Silverfish spawn from broken infested blocks, which generate in strongholds, igloos with basements, woodland mansion fake portal rooms, and mountains biomes. Silverfish do not appear if the block is broken with Silk Touch.


When spawning from spawners, they can spawn only in light level 11 or lower. They also cannot spawn within a 5 block distance of any player. Silverfish spawners naturally generate in end portal rooms in strongholds.


Silverfish are the fifth smallest mobs in Minecraft, after the baby turtle, the baby bee, normal pufferfish and the endermite; their height is less than that of a slab.

Silverfish can "call" other silverfish in the area upon being hit. These silverfish can see through walls and pathfind until they reach the player.

When idle, silverfish enter a nearby stone, cobblestone, stone bricks, mossy stone bricks, cracked stone bricks, or chiseled stone bricks block, transforming it into the respective infested block if /gamerule mobGriefing is set to true. They cannot infest mossy cobblestone, despite being capable of infesting both mossy blocks and cobblestone, and they also cannot infest slab and stairs variants of these blocks. They also (as of 1.15.2) are unable to infest andesite, diorite, granite, or smooth stone.

When they suffer poison damage or damage inflicted by the player, and survive, they may cause other silverfish within a 21×11×21 area to break out of their monster eggs. The player can, therefore, prevent other silverfish from appearing by killing them in one shot.

Silverfish, being arthropods, take more damage from tools with the Bane of Arthropods enchantment.

  • In real life, silverfish are small, relatively harmless, wingless arthropods that are often found in dark areas in buildings and the wooden pilings of seaside piers and trees. They are infamous for damaging paper-based products.
  • Unlike most Minecraft mobs, they do not have a plush toy.
  • They appeared in the April Fools 2.0 update as the Redstone Bug.
  • In Bedrock Edition, letting a silverfish enter regular stone bricks turns them into infested stone instead of infested stone bricks.
