Pseudotropheus perileucos is different from other striped species by its faded, often interrupted, horizontal stripes in males. In general the males have a blue body getting darker to black near the belly and the dorsal fin. The dorsal fin has a small white edge. Females have very light-colored bodies, getting yellow near the belly and dorsal fin. The dorsal fin often is black with the same white edge the males have. P. perileucos is the only striped species in which females may be white.
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.
This measure is a relative value, comparing a single species against all
This only accounts for maintanence in the aquarium and not breeding
1 = easy and forgiving, 5 = extremely challenging.
