I'd love some enclosure shots. Those guys look stunning! Nice work.
Your guesses regarding the sexes appear to be good ones. Not sure about the 'male' though as it too may be a girl.
Here is a tip regarding the fungal issue...before applying the cream, wipe down the plastron with rubbing alcohol. This helps dry the site and prep it for the anti-fungal cream. In addition, check the scutes on the legs as they too can be infected with the fungus---but withhold food if you treat the front legs to avoid ingestion of the meds.
