Key differences: This is one of the most common Pygmy Sunfish species. Differentiated from other Elassoma species by specific color patterns (e.g., number and intensity of vertical bars, presence/absence of iridescent spots) and meristic counts (fin ray counts, scale counts). Males typically have distinct vertical bars and iridescent blue spots.
Carolina Pygmy Sunfish
Elassoma boehlkei
Key differences: Distinguished by its unique color pattern, particularly in breeding males, which often display a more uniform iridescent blue-green body with fewer distinct bars compared to E. evergladei. Geographic range is also a key differentiator, being restricted to specific drainages in the Carolinas.
