This is a particular profile we have to deal with, it was known as Haplochromis sp. "double stripe", van Oijen & Witte described Haplochromis thereuterion in 1996. Its general body shape evokes an arrow, a torpedo, a fish shaped for the speed; This is mostly a surface dwelling species eating insects larvae and adults in the wild. It has been recorded from the northern Mwanza Gulf at Anchor Island, Kissenda Island, Hippo Island, Nyegezi Bay, Nyegezi Rocks, and some recent catches seems to show an increasing population of this species at Makobe Island. It lives at Kissenda Island with the more oriented sandy species Haplochromis tanaos (van Oijen & Witte,1996) that is very close in male coloration and general body proportions. They are both segegrated by their foods(H. tanoas is a zooplanctivore), by their micro habitats (rocks/sand), by little details of their male coloration ( H. tanaos is more dark blueish on the upper body, black in the ventral part), teeth forms and little morphologics details of the jaw. It's a relatively peaceful fish living better if kept in good number of males and females in a 55 g tank. Males keep a little territory and try to attract the females in their little spawning pit. One should avoid keeping them with robusts mbipis (rock dwelling fish) because of their placidity, they won't defend their hole in front of aggressive fishes and surely, they won't spawn. Its elongated shape makes this fish quite unique in the insects eaters species, its coloration is very attractive and its gentle manners are another good point to show.

 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.
