Ps. Williamsi is the type species of the genus. They are found all over the lake and are one of the bigger species and it is believed that all of the unidentified williamsi types may in fact belong to a single species with a wide distribution. Males are mostly blue with a black submarginal band on the dorsal fin. Females can vary from brownish-yellow to grey, but they all have two rows of black spots.
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
