Okefenokee pygmy sunfish
(Elassoma okefenokee)

The Okefenokee pygmy sunfish, Elassoma okefenokee, is a species of pygmy sunfish found in southeastern United States, where it prefers waters with dense vegetation growth in the Altamaha drainage in southern Georgia south to Lake Okeechobee, Florida, interior lake basins in north-central Florida, and upper Suwannee, Withlacoochee, and Hillsborough river drainages on the Gulf Coast of Florida.

This species can reach 3.4 cm (1.3 in) in total length.

Description
The Okefenokee pygmy sunfish is an olive green color fish with brownish-red mottling across the body, mixed with bright blue colors. Elassoma okefenokee differs from its close relative Elassoma gilberti by only having three preopercular canals (gilberti has, on average, four). The average number of anal fin rays is seven in E. gilberti whereas E. okefenokee has 8. The female E. gilberti often expresses a blue patch of color behind her eye and on her body, while the E. okefenokee does not.

It has dark brown bars on the side of the body that are darkest posteriorly and many black specks and spots on the head and body. There are two large cream-colored spots at the caudal fin base and the lips are typically light-colored in the front except in large males. Large males are shiny black with bright iridescent blue bars on the side of the body and below the eye.

Habitat
Elassoma okefenokee is a freshwater, demersal fish which spends its time in dense vegetation growth in waters with a pH range of 6.0-8.0 and a dH range of 5-unknown. Their preferred temperature range is 18 °C - 28 °C.
