The Silverfish is a mob in Minecraft. These small mobs have silver skin and black eyes. They are usually found in strongholds.
Silverfish spawn from infested blocks, specifically broken infested blocks. These are generated in strongholds, woodland mansions, and in false portal rooms.
Silverfish spawners naturally occur in strongholds and end portal rooms. However, they can also spawn on certain stones, depending on light level. Generally, the light level cannot be more than 11 or less.
Silverfish do not drop any items in the game, but they can damage players. It is possible to reduce the size of their swarm by using a bow, or by splashing potions.
Silverfish are not known to carry disease-causing pathogens, but they can damage players with low health. The silverfish swarm can become extremely large, so it can overwhelm a player.
Silverfish are attracted to damp dark areas. They are very easy to kill, but they can be a problem when mining.
They can also be a problem if you are using a tamed wolf. The silverfish can dismantle your newly built house.
You can find silverfish in the Extreme Hills Edge biome. These blocks do not spawn in other biomes.
If you are interested in changing the way silverfish behave, you can install the Mob Properties mod. There are also mods that allow you to change their health.
Silverfish do not spawn within five blocks of any player. Also, they cannot spawn on slabs, mossy cobblestone, or stairs.
