Picture #2 is what is called in the trade a "Neon jewel" or "Turquoise jewel". It is very similar to the common jewel in the hobby, Hemichromis guttatus, and really differs only on having more bright blue spots. It is not known exactly what or where the fish comes from. These are all possibilities: 1) line bred strain of common jewel. 2) regional variant of common jewel, but with unknown collection point. 3)closely related species with unknown collection point. 4) produced by hybridizing different Hemichromis species.
H. lifalli is just as mis-identified. Virtually all the fish called this in the trade are strains of very colorful H. guttatus. The real H. lifallili is what used to be known in the hobby as H. sp. "moanda". It is easily distinguished from H. guttatus A picture of H. lifallili: http://www.borstein.info/profiles/west_africa/hemimoanda.html
Picture #3 isParalibidochromis suavagei commonly called a "Rock Kribensis".
The common jewel in the hobby is Hemichromis guttatus. This info has been made known by ichthyologist Paul Loiselle over 40 years ago and has been confirmed by ichthyologist Anton Lamboj, many times over the years, though the mis-identified name H. bimaculatus continues to be used on some internet sites and out dated books. The real H. bimaculatus has very rarely been imported and really not something you are likely to ever encounter the hobby. It can be distinguished, as pictures of wild caught specimens show a fish virtually devoid of bright blue spots.Haplochromine guy said:Jewel Cichlid (Hemichromis bimaculatus) middle pic or Hemichromis lifallili is more likely option.
