OK, so I have this "female", originally a supposed wild-caught unidentified apisto fry. Size-wise she is not huge (maybe 2" SL), but is way bigger than any apistogramma that I have ever seen. She has caught up in size to some rams in the same tank. Shy, not agressive at all, except in defending her small flower pot cave. Looking at the photo, she does not appear to me to be very apistogramma-like at all.
