Eric, The growth on the Nannacara, does is it shaped like a lumpy piece of cauliflower? If so, it's probably caused by the Lymphocystus virus. Like most viruses, you can't treat it with antibiotics, but if the fish is otherwise strong & healthy the growth will disappear naturally once the fish is put in quality water conditions. I've never had N. transvestitus, but like other Nanochromis they form pairs when ready to breed and are not polygamous. If your tank can handle them adequately, I'd suggest getting another male & female. Then see who pairs off.
