Well the third photograph is a
Hoplarchus psittacus, True SA Parrot Cichlid, which you won't find over here.
Keep an eye out for Severum, there are various different colour 'styles' getting around. How pure these are to natural strains of Heros efasciatus can't really be ascertained. Best I can do is post my three Severum.
Regular style female like you've posted in your first photo. Plain body scaling. She was hugely dominant and would often be in semi-breeding dress that was basically black/olive.
Smaller male which I would classify as the same variant as the larger male below. Lots of red and fluorescent blue as you can see. Will probably grow up to be a better quality version of this guy..
Note the scale patterning (possibly only present in males) and the subtle blue patterning on the face.
Now I don't have these fish anymore. They were sold to someone about 6 months apart who was looking to get into breeding them.
Original female and the last male I linked. Note vibrant colouration on the male and females breeding dress.
Hope that helps in some way. The key to buying Severum is to not be overly keen and shop around. As they're reasonably common, you can afford to go to a few shops looking for another species and pick out nice Severum if you come across them.
The last 2 males were sexable at about 2", and had noticable blue in the face.
