IMPORTANT
Keeping fish in an aquarium requires an ethical and responsible approach that prioritizes animal welfare. Purchasing fish for an aquarium should never be an impulsive decision. It is essential to understand the specific needs of each species, including water quality, aquarium size, behavior, and diet. Only fish with similar water quality requirements should be kept together in the same aquarium.
A Little More Information...
Otopharynx sp. Nova Blue is a haplochromine cichlid from Lake Malawi, sold in the aquarium trade under the name Long Nose. This aquarium form is especially sought after for its slender profile, extended snout and the metallic blue coloration shown by mature males. The trade name Nova Blue should not be treated as the name of a formally described species. It is fairly uncommon in regular availability and is best suited to aquarists familiar with African cichlids. A rocky layout, alkaline water and a varied diet help support its colors and natural behavior.
General species description
Otopharynx sp. Nova Blue is traded as an undescribed form of the genus Otopharynx, among the haplochromine cichlids of Lake Malawi. It is mainly recognized by its relatively elongated body, narrow head and distinctly extended snout, the feature behind the common name Long Nose. Mature males may develop a vivid blue coloration, while females and juveniles are usually more subdued. Its behavior is typical of a medium-sized cichlid: active and territorial during breeding, but generally compatible with similarly sized tankmates. Its commercial availability is intermediate: it is uncommon, without being impossible to obtain.
Geographical origin and biotope
Country reference: Malawi. Otopharynx sp. Nova Blue is associated with the fish fauna of Lake Malawi, a large alkaline freshwater environment in the Rift Valley. Like many lake haplochromines, it is adapted to warm, mineral-rich and well-oxygenated water. An aquarium based on this habitat should emphasize stacked rocks, open swimming areas and fine sand. Vegetation generally plays a secondary role compared with rocky formations and open zones. A temperature of 24 to 27 °C and a stable alkaline pH are suitable for its care.
Precise location and local name
The trade and import name Otopharynx sp. Nova Blue is used for this aquarium form, while Long Nose is its main vernacular name in the aquarium hobby. The term Nova Blue mainly describes its sought-after appearance rather than a geographic locality. Keeping the complete trade name in aquarium records helps prevent confusion with another population or another blue form of Otopharynx. For aquarists, identification therefore relies primarily on the combination of an elongated snout and blue coloration, rather than on a collection-site name.
Appearance and physical characteristics
Otopharynx sp. Nova Blue has a streamlined, laterally compressed body suited to active midwater swimming. The head appears longer and narrower than that of several popular Malawi cichlids, with a particularly visible elongated facial profile in adults. Mature males generally show a metallic blue coloration, sometimes extending across the head, flanks and fins. Females are more discreet, often silver-gray or brownish, while juveniles show less developed colors. Maximum adult size is approximately 15 cm; actual size depends on sex, diet quality and available space.
General diet
A varied diet suits Otopharynx sp. Nova Blue: quality Malawi cichlid pellets, frozen foods such as mysis or brine shrimp, and some formulated vegetable matter. Meals should remain moderate and be offered regularly to support growth without overloading the digestive system. Juveniles benefit from small, frequent portions, while adults may be fed once or twice daily. Avoid excessive high-fat foods and exclusively meat-based feeding. A balanced diet supports blue coloration, vitality and good body condition while reducing risks associated with overfeeding.

In your aquarium
To maintain Otopharynx sp. Nova Blue successfully, provide a spacious aquarium, efficient filtration and alkaline water with stable parameters. Rocks should offer shelter without obstructing swimming areas. Choose African tankmates with similar size and temperament, and avoid excessively aggressive species or mixes of very closely related forms. A varied diet, regular water changes and a reasonably stocked aquarium will help keep the fish healthy. Water stability and territorial management are the two most important factors for preserving its blue coloration and natural behavior.
