These are
not hybrids but all genuine as far as i can see.
The problem is, i believe, there are still a number of undescribed species which people try to pigeon hole into one of the known names.
I was hoping Birger might have chipped in by now....where are you buddy??
Pics 1,3,5,7,9 & 10 all look like typical Lucipinnis (thanks to Mats for pic numbering

)
Pic 13 reminds me of species 2 - the white zambian polli apart from the white leading edge to the dorsal
The fish in pic 11 looks like a fish being sold over here labelled tanganicae or dhonti by some retailers (& looks like it is a small individual)but again a white leading edge to the dorsal
Pic 2 looks to have too many body spots for Lucipinnis so therefore a slighty atypical petricola.
Pic 4 quite looks like my Irsacae but again a white leading edge to the dorsal.
