I am interested in shoaling behavior in mudminnows, where a shoal is a group of fish that swim around together. I want to examine the following hypothesis: mudminnows form shoals to enhance (improve) food discovery.
Create a prediction based on the hypothesis
Mudminnows will find feeding zones more quickly when in shoals.
