Very realistic looking fish behavior based on simple variables and tracers, a simple and beautiful solution to most simple, realistic underwater environments.

This system is about fish behavior, reproduction through automatic spawning copies with random sizes and behaviors preseted in species settings, population control at locations according to the basic settings, or for each specific location. Includes three types of fish to demonstrate the system. One of them, sprat, is with generation in particles for a lower load for system. And can be used to generate large crowds when needed.
