Habitat selection in drift feeding stream fish

Public

I studied Nanacara anomala, foraging in an artificial stream. The fish chose between a gradient of water velocities under three group sizes. I theorize that fish should be less selective about their foraging patch as group size increases. During trials I measured the number of fish in each patch. I concluded that the variance for my smallest group size was significantly smaller than the variance for the two larger group sizes.
