Fathead minnows, crayfish, and possibly golden shiners also reproduce in lake as well. Common shiners are known to hybridize with other shiner species. These include red-sided shiners, sculpin, suckers, and speckled dace. The presence of redfin shiners does not seem to bother the sunfish. Living in freshwater, emerald shiners are benthopelagic. Golden shiners live in large groups (shoals) that roam widely. Golden shiners prefer quiet waters and are therefore found in lakes, ponds, sloughs, and ditches. Fireflies are known as "shiners" in the Underland. Given the small size of spottail shiners, many different species of fish prey upon them. These competitors can include other species of shiners, yellow perches, or white perches. There are certain parasites that also affect the life of these shiners. The parasites are also found to affect the immune system in spottail shiners. The term shine originates from young African American shoe shiners who would dance for money. They are known commonly as eastern shiners. The maximum reported age of emerald shiners is four to five years.
