A model of fish in a pond eating algae. Choose one of the Create Fish buttons, then Run to run the simulation.
Create Yellow Fish: only yellow fish will be created, so you can focus on overall population sizes.
Create Multi-Color Fish: fish of 4 different colors will be created, but the colors are cosmetic only.
Create Multi-Trait Fish: the different colors of fish also have slightly different reproductive strategies. Red fish have many, small offspring, while magenta fish have fewer, larger offspring.
Q: Is there something you could change about the environment or algae that might make a different color more likely to survive longest?
