There are a total of eight species of wild fish in West Creek. Brook trout and brown trout both inhabit West Creek, although brook trout are slightly more common than brown trout, with nine brook trout and only seven brown trout being observed in a 2010 or 2011 electrofishing survey. Trout are more common upstream of the Pennsylvania Route 239 crossing of the creek than downstream of it. The most common fish in the creek are sculpin, eastern blacknose dace, and cutlips minnows. In the aforementioned electrofishing survey, a total of 81 sculpin, 34 black-nosed dace, and 17 cutlips minnows were observed.
