Dollar Sunfish
Lepomis marginatus · also called dollar sunfishes
Tucked among dense aquatic vegetation in a quiet southeastern wetland, a dollar sunfish goes about its business barely noticed, its small, round, coin-shaped body easy to overlook next to the larger sunfish species sharing the same water.
Overview
The dollar sunfish, Lepomis marginatus, is one of the smallest members of the sunfish family, native to quiet, vegetated wetland and slow-stream habitat across the coastal plain of the southeastern United States. Its coin-like shape, diminutive size, and preference for dense cover make it one of the more genuinely overlooked small sunfish species most anglers rarely target directly.
Small enough to live up to its name
Few fish carry a name as literally descriptive as the dollar sunfish, whose small, round, flattened body really does bring a coin to mind at a quick glance.
Status
Least Concern — widespread and common across suitable quiet, vegetated wetland habitat throughout the coastal plain of the southeastern United States.
Dollar Sunfish: common questions
Why is it called the dollar sunfish?
This species takes its common name from its small, round, flattened body shape, roughly comparable in size and outline to a coin, a fairly literal naming choice reflecting just how compact this sunfish species is compared with several larger relatives.
How big does a dollar sunfish get?
It is one of the smallest members of the sunfish genus, rarely reaching more than a few inches in length even as a full adult, considerably smaller than well-known relatives such as the bluegill or redear sunfish.
Why is the dollar sunfish rarely noticed by anglers?
Its diminutive size combined with a strong preference for dense aquatic vegetation means the dollar sunfish is often overlooked entirely in favour of larger, more conspicuous sunfish relatives that anglers more commonly target.
Do dollar sunfish change colour during breeding season?
Yes, a breeding male can display noticeably brighter blue and orange colouration than the duller females, a seasonal colour change typical of several sunfish species during their spawning period.
