Try PMing jetajockey. He seems to be the go to on alot of native fishes and may be able to point you in the rite direction for acquiring one of the pygmy sunfish species. Goodluck and keep me posted. I've been considering the idea of a 15gal. Species biotope tank for one of the pygmy sunnies so I'm really interested in what route you take!
