The blueish sheen is typically seen in amatitlania siquia, rather than nigrofasciata (convict). They are very similar species, but the temperament is quite a bit different. HRP's are typically more laid back. For a while HRP's were thought to be just a collection point of nigrofasciata, and weren't officially given a species name until fairly recently (siquia).
The first picture in the bags are siquia. The second and third picture are of nigrofasciata. I'm assuming the second/thrid picture are different fish from the first? Otherwise they settled in something weird lol
