The Fountain darter is a small fish usually no bigger than a few centimeters that lives near the springs where they can hide in the green algae (Texas Parks & Wildlife, Fountain Darter). Based on percent frequency of occurrence of food items in fountain darter stomachs sampled from the San Marcos River, juveniles and small fountain darters feed primarily on copepods; medium-sized feed mainly on dipteran and ephemeropteran larvae, and fully mature darters prefer ephemeropteran larvae. McDonald, D.L., T.H. "As physical phenomena serving as the material basis of hierophanies (appearances of the divine), fountains may be described as the flowing of pressurized water up and out through an aperture from some hidden depth below the earth's surface. E. fonticola and E. proliare are similar, but differ in that the former species has a short lateral line with 0-6 pores, 1 anal spine, and cross-hatching on upper and lower side, while the latter species has a short lateral line with 0-9 pores, 2 anal spines, black or brown dashes along side, and spots on upper and lower side (Page and Burr 1991).

Another critical component of fountain darter habitat that is presently unknown is the relationship of macroinvertebrates (fountain darter’s main food source) to low-flow conditions.
