ok ok .. Here's what I think

1) Pseudotropheus sp. blue zebra
2) Pseudotropheops tropheops - "unknown location or variant".
3) Pseudotropheus greishakei - but the pics are a little hard to verify as I notice a yellow tinge on the dorsal.
4) Definitely a hybrid.. Peacocks don't have a horizontal line.. only vertical. Protemalas sp' presumably.
5) Hemichromis sp. hybrid - Most if not all are hybrids.. no one knows distinctly of aquarium strains .. coz they look like bimaculatus, lifalili, cristatus etc. and furthermore its a species that hybridises easy and breeds like rabits.
