Haplochromis cyaneus was previously known as Haplochromis sp. "blue rockpicker". It was described as Haplochromis cyaneus in 1998 by Seehausen, Bouton & Zwennes. It has been found in rocky habitats from Sengerema region (Chamagati) to Speke Gulf (Nanzio, Makobe) with a very scattered distribution; it lives in waters from 1 m to 6 m deep slightly offshore from gentle to very gentle slopes with small to very small boulders. The major part of its diet is composed of blue green algae and to a lesser extent insect larvae. It lives in sympatry with H. flavus (yellow rockpicker) but its diet varies slightly (more algae) and in all the habitats, it's more abundant than the yellow sibling species H. flavus. It shares its habitat with many others algae scrapers of the Neochromis, Mbipia species but also some others species such as H. sp. "short snout scraper", H. sauvagei. We have here a very rare species being found at only three localities in the eastern part of the lake. Its bright blue coloration with vivid red fins makes it a truly beautiful fish to keep.
Pronunciation: Refer to our Pronunciation Key for an explanation of the phonetic symbols.
Habitat: This is the primary location where the cichlid is found and is a generalization. This does not mean a fish cannot be found in other habitats.
Diet: Many cichlids specialize in eating one type of food; notwithstanding, some of these specialized feeders are flexible and can be opportunistic feeders.
Temperament: This describes the overall demeanor of a cichlid toward other tankmates that are of a different species. Consider that there is variability in temperament due to various factors, including aquarium size, tankmates of similar appearance, stocking levels, and order of introduction. There may even be some variability among individual specimens.
Conspecific Temperament: This describes the overall demeanor of a cichlid toward other tank- mates of the same species. Consider that there is variability in temperament due to such factors as aquarium size, stocking levels and order of introduction. There may even be some variability among individual specimens.
Maximum Size: This is in regards to total length (including the tail) of typical aquarium specimens. Wild specimens may not attain this size, or may in fact grow larger than aquarium raised individuals due to various factors. Also consider that this is the typical maximum size and there are exceptional individuals that will exceed it.
