Actually according to Inchworm, as I understand it, haraldschultzi have the orange fins, and they look almost exactly alike, except the haraldschultzis reverse the black/white thing, and the sterbai are about an inch smaller.
Anyway thanks! they are real cuties. They look awesome against the black sand and with the albino longfin pepper babies.
I will have to watch for the water quality now though. The tank is very stocked.
