Every single one looks like the real njassae to me; despite the different humerals.
the overall shape, finnage and dimensions are pretty characteristic for njassae; not like the ugly hybrids flooding the market.
I have a strong suspicion that njassae -like for example multipunctatus or petricola- comes in varieties.
we already are familiar with a "big spot" (first and fifth pic) and a "small spot" (second and third pic) wich I've seen before in live fish myself; and ofcourse, living animals aren't the "carbon copies" scientists sometimes wish then to be to separate the species.
but the first humeral on top of the post is odd. it hasn't got the curved upper line, like all the others, it's more of a "spearpoint" shape, than the "hook" shape of all the other humerals, wich is typically njassae.
