# Common Goldfish vs Koi: Who Would Win?

Common Goldfish vs Koi is too close to call. Our 3-round simulation gives Common Goldfish a 49% chance and Koi 51%, which is not enough for either to claim the win.

The simulation puts both animals on neutral ground. In the wild, terrain, the size of the individual animals and plain luck would all change the result.

## Verdict: Too close to call
- **Win probability**: Common Goldfish 49%, Koi 51%
- **Decisive weapon**: Evenly Matched Evolutionary Countermeasures

### Round 1: Opening Clash & Speed

Koi blindsides Common Goldfish right off the bell, leveraging keen predatory cunning (40 vs 40) to dictate the pace of the engagement.

### Round 2: Clash of Superpowers

An earth-shattering clash as Common Goldfish's "Makes ethanol to survive without oxygen, and sees four colors including ultraviolet" crashes directly into Koi's "In one study, sought out a human hand for touch even after a full meal", sending shockwaves through the arena.

### Round 3: Final Resolution

After three grueling rounds, neither creature can establish a decisive edge. Both combatants retreat to neutral ground with full mutual respect.
