Silverfish can spawn from silverfish blocks and monster spawners. They are also able to spawn, albeit rarely, underground in Extreme Hills Biomes, inside of certain blocks. In the latter case, they can only spawn in light level 11 or lower, except on top of stone blocks, where they can spawn at any light level. They also cannot spawn within a five-block distance of any player. These restrictions only apply when spawning from a monster spawner, and not from a Silverfish block.
The blocks in which silverfish hide look identical to stone bricks, cobblestone, or regular stone, but take slightly more time to mine than normal with a Pickaxe, and will take noticeably less time to mine without one. When the block is broken, Silverfish will pop out and attack. Destroying one of these blocks via Creepers or TNT will kill the silverfish instantly, before it has time to emerge. In regular gameplay, Silverfish blocks occur rarely. If left alone, silverfish can re-enter some blocks, namely cobblestone, regular stone, and stone bricks.
When attacked, Silverfish may awaken nearby Silverfish within a 21x11x21 block area. This can lead to a terrifying swarm if there are enough in the vicinity. An uncontrolled swarm can quickly destroy dozens of stone bricks within a Stronghold. They scurry away after the player moves a short distance.
Silverfish can cause damage to a player. This occurs when a silverfish is touching a player and a change of the Y-coordinate (elevation) of either the player or silverfish occurs. This can easily kill a player, since - in a confined space - receiving damage causes the player to perform a short "hop," which counts as a Y-cord change. This allows the silverfish to damage the player again as the player is coming back down from the initial "damage hop". Formerly, Silverfish could not damage the player directly, but would scurry towards the player and push them around, with the tendency to be aggravating and potentially dangerous (e.g. when around Lava/Fire).
It is advised to avoid conflicts with silverfish altogether, as they will simply generate a massive swarm that can easily overwhelm an inexperienced player. If the player does, however, choose to challenge silverfish, it is advised that they wear Armor, as silverfish can quickly deal massive amounts of damage as the swarm grows. Melee weapons are advised, as silverfish are the smallest mob that naturally spawns. If the player is experienced with a bow, then using ranged combat may reduce the size of a swarm.
A simple tactic to combat a swarm of silverfish is to simply build a two-block high pillar and attack from there, as silverfish do not have any range and only deal damage via contact.
- The I.D. for the Silverfish block is 97, and can be hacked in through mods or by using the /give command in multiplayer, levels with cheats activated, or through LAN.
- Silverfish, along with Endermen, Had a placeholder sound in Beta 1.8 but they got their own sounds on the 1.0 Update. Before 1.0, Silverfish shared the same sound with Spiders.
- Silverfish can be spawned in Creative Mode using the Silverfish Spawn Egg. The silverfish blocks can also be used and are found under "decoration blocks".
- If a silverfish block is destroyed in Creative mode, a silverfish will still pop out.
