Habitat: Shallow, inshore areas wherever rocks are found

The most obvious difference between N. nigricans and N. rufocaudalis is that males of this species lack the red tail and anal fin. Both exhibit a dark blue body coloration. Several jet-black vertical bars are evenly spaced along the flanks. The dorsal fin is a metallic blue, outlined by a bright red stripe. Females and sub dominant males are similarly patterned. A broken series of blotches along the lateral line is over a background of an earth-brown coloration. Nicknamed the "Victorian Tropheus", this species is similar in many ways. It is an an epilithic scraper. Provide plenty of foods high in algae content, such as seaweed flakes and spirulina. An aquarium of 100+ gallons is recommended.
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.
