hi On the list yu posted, H."Prognatochromis" macrognathus seems extinct in the wild, yu'll hardly get some pix, it's a piscivore species that reached 25 cm long.
Haplochromis"Paralabidochromis"chilotes is an insect eater, well distributed in the all Victoria lake, he lives on differnts biotops as rocky reefs, sandy zones and planted aeras. Its hunting method is to check the insect larvaes at te basis of the rocks.
H."Macropleurodus bicolor" is an shell eater eatinf melanoides and plannorbs, it's an oral extractor, I think it's a very endangered species, it was collected at many places before the Nile perch aera, it leved over the muddy and sandy zones;
H.elegans is a fish from Edward and George lakes, an insect eater and zooplancton feeder that wasn't exported in the hobby, it seems not to be endangered.
