Hi Sheila -- here ya go: Pygmy Sunfishes - NANFA Forum
Check out Erica Wieser's very informative (and long) thread on E.gilberti (Gulf Coast pygmy) which is nearly identical to E. okefenokee. (Erica is a grad student at WFU, not far from you). She also has some great videos of them dancing and spawning.

The ones you bought may actually be gilberti - ask the seller where they were collected. In Florida E.okefenokee is mostly east of I-75, and E.gilberti is mostly west of I-75. The Suwanee River near I-75 has both species.

I've been keeping a colony of gilberti for about 12 years. My avatar pic is from 2005, and I still have his descendants. I feed them chopped live blackworms, grindal worms, fresh-hatched BS, and mosquito larvae. Babies I feed rotifer & paramecium mixed culture until they can eat BS. They will not eat dry food. Lots of fine-leaved plants, pH 5.5 to 7.5, hardness 2 dGH (35 ppm) or higher. My water is soft, but Erica had hers in very hard water when she lived in Ohio and they did fine.

 

I've had best success with Pygmies in small species tanks with java moss, live foods, natural light from a window if possible and here's the trick, an under gravel filter.

My theory is the fry are so small and fragile, the fall down into te gravel where they get protection, oxygen, microorganism to eat and a place to metamorphose.
