An interactive HTML canvas simulation of a koi pond, where animated fish swim naturally and dynamically respond to user interactions.

This is an interactive HTML canvas simulation featuring koi fish swimming and reacting to user input.

Realistic Movement: 12-segment articulated spine creates natural swimming motion with flexible, flowing tails

Interactive Feeding: Click or tap to drop food particles - fish detect and swim to eat them

Mouse/Touch Reactive: Fish avoid cursor when approached, then resume natural wandering behavior

Authentic Koi Patterns: 10 randomized color varieties based on real koi breeds

Smooth Physics: Progressive body flexibility with tails moving more dramatically than heads
