Silverfish are hostile animals that will appear only when a player is mining what he thinks is a block of stone, although it is actually a different type of stone. They have the appearance of an insect, their small body is silver-gray and their eyes are dark.
Behavior
They always appear unexpectedly and move on the ground quite quickly, moving their body from right to left, similar to how snakes move.
Their attack is not very powerful, however they attack the player directly, pushing him, which can sometimes be quite dangerous, especially if we are in an area with ravines or high falls.
The Silverifsh attacks when the blocks that generate them are broken, otherwise they do not appear in the world.
Spawning
Silverfish appear only where there are blocks, similar in appearance to stone, that summon them. The impossibility of recognizing one of these stone blocks means that Silverfish always appear by surprise.
They will not be generated anywhere in the world, but can be found hidden inside stone blocks, in the Extreme Hills biome, in the Stronghold and in the basements of the igloos.
