The Mob Cap in Minecraft: Why Mobs Stop Spawning
The mob cap limits how many mobs spawn naturally. On Java each category has its own cap per player: 70 monsters, 10 creatures (animals), 15 ambient (bats), 5 axolotls, 5 glow squid, 5 water creatures and 20 water ambient (fish). Bedrock uses a global cap of 200 plus smaller population caps per area. Persistent mobs, such as named ones, do not count.
What are the Java mob caps?
| Category | Cap | Examples |
|---|---|---|
| Monster | 70 | Zombies, skeletons, creepers, spiders, endermen |
| Creature | 10 | Cows, sheep, pigs, chickens, horses |
| Ambient | 15 | Bats |
| Axolotls | 5 | Axolotls |
| Underground water creature | 5 | Glow squid |
| Water creature | 5 | Squid, dolphins, nautiluses |
| Water ambient | 20 | Cod, salmon, tropical fish, pufferfish |
Java has a global cap scaled by loaded chunks and a per-player cap for mobs within 128 blocks of each player.
Why does the mob cap matter for farms?
If 70 monsters are already loaded around you, in caves for example, no more spawn, so a mob farm makes nothing. Light up or slab nearby caves, build farms high in the air or over the ocean, and stand at an AFK spot so most mobs near you are in the farm. See mob farms and mob spawning.
Which mobs do not count?
Persistent mobs: named mobs, mobs holding picked-up items, mobs riding something, and mobs from structures. Villagers and golems are in a separate category with no cap. Spawn eggs, spawners, breeding and /summon ignore the cap too. Despawning: mob despawning.
How does the Bedrock cap work?
Bedrock caps environmental spawning at 200 mobs globally, and population caps limit each category within a 9 by 9 chunk area around the spawn attempt. Mobs from breeding, eggs, spawners or commands are not limited. Name tags also keep mobs out of the count; see name tags.
