Although specimens of Divandu albimarginatus were collected as early as 1959 and again in 1986, is was not until Victor Mamonekene collected this cichlid in 1990 and 1992 that it was finally given its due. In 1993, the late Dr. Guy Teugels and Mr. Victor Mamonekene noted a new cicihld collected in the Mayombe Forest in Congo-Brazzaville. From 1991-1992, they had been working in the Mayombe region to study the fishes of the biosphere reserve of Dimonika, as part of a larger project encompassing the flora and fauna of this protected area. Dr. Teugels explained to this writer that although their new discovery bore a resemblance to Chromidotilapia and to Limbochromis, it could not be assigned to any published genus. Doctors Lamboj and Snoeks named this central African cichlid, Divandu, the local name for Chromidotilapia-type cichlids, albimarginatus, from the Latin "albus" (white) and "marginatus" (edged or bordered), in reference to this species' "white margin on the lower edge of the caudal fin in preserved specimens" (Lamboj & Snoeks, 2000). D. albimarginatus can be distinguished from the other species of the chromidotilapiine lineage, in part, by a series of combined morphological characterists including, but not limited to, low levels of sexual dimorphism and dichromatism (coloration), a longer first pelvic fin ray in both sexes, 2 1/2-3 scales between the highest point of the upper lateral line and the dorsal fin base, and a reduced number of scale rows around the caudal peduncle (12 vs. 14-16 in some other species). For coloration, please refer to the photos above. –Randall Kohn (with special thanks to the late Dr. Guy Teugels and hobbyist Florent de Gasperis who collected D. albimarginatus himself!)

 Key To Species Profile Terms
 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.
 Difficulty: This measure is a relative value, comparing a single species against all other cichlids.
  This only accounts for maintanence in the aquarium and not breeding considerations.
  1 = easy and forgiving, 5 = extremely challenging.
