Neochromis omnicaeruleus is an aggressive fish. Two males can't live together for long in a tank less than 100 gallons. Along with Mbipia lutea it is one of the most territorial Victorian mbipi. This being said, it's an amazing fish when OB (orange-blotched) or WB (white-blotched) colored, you may find some males that are blue -white and black blotched, some are orange, green or yellow blotched. The Makobe population in particular has more blotched females than plain colored females. This fish is found at a depth of 1 to at least 6 meters, and lives in gently to steeply sloping areas with large to small boulders. N. omnicaeruleus consumes blue green algae and diatoms on the rocks. Its dentition is close to the Neochromis rufocaudalis but differs in a few small details. It shares its habitat with many other algae scrapers such as Neochromis rufocaudalis, N. gigas, Mbipia lutea, N. sp. "Juma scraper", N. greenwoodi. There are some morphology differences among populations of the omnicaruleus species, the population around Ruti Island is red colored in the pelvic fin and caudal fin with a white anal fin, while the Makobe Island Population doesn't have any red on any fins. It is important to keep these populations segregated in captivity as they are separated by large and deep open water in the wild.

 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.
