Electric Blue Hap

Sciaenochromis fryeri

Cichlids - African

The Electric Blue Hap is a striking Lake Malawi cichlid. In the wild, they are specialized piscivores that hunt the fry of other cichlids among the rocks. Due to extreme sexual dimorphism, mature males develop a brilliant metallic blue coloration, while females remain a drab silver-brown. They are best kept in a large, hard-water aquarium either as a single showpiece male in an 'all-male' Hap/Peacock display, or as a single male with a harem of multiple females.

Electric Blue Hap Varieties

Each variety inherits the species defaults above. Only differences are highlighted.

Male

Brilliant metallic blue, sometimes featuring a white or orange blaze on the dorsal fin (e.g., the 'Iceberg' morph). Highly territorial toward other males of similar color or shape. Strictly one male per tank is recommended to prevent fatal disputes, unless the tank is exceptionally large and overstocked to manage aggression.

Differs in 2 traits from base species

Also known as: Show Male, Iceberg

TemperamentAggressive
StockingSolo only

Female

Drab silver, grey, or brownish coloration. Significantly less aggressive than males. Typically kept in a harem ratio of 1 male to 3+ females if breeding is desired. Multiple females can co-exist peacefully.

Differs in 2 traits from base species

Also known as: Drab, Breeder Female

Adult Size13 cm
TemperamentSemi-Aggressive

Albino (Male)

An albino genetic morph of the male, featuring an icy-blue to nearly white body with red eyes. Retains the same predatory and territorial behaviors as standard males.

Electric Blue Hap Care Guide Summary

The Electric Blue Hap, scientifically known as Sciaenochromis fryeri, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 16 cm and have a fusiform body shape with a moderate growth rate. Classified as aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a high level of biological waste.

To thrive, the Electric Blue Hap requires a freshwater only aquarium with a minimum volume of 200 litres and a tank length of at least 120 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 7.88.6 and a general hardness of 1025 dGH. A moderate water flow is preferred.

Due to its specialist needs, the Electric Blue Hap is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 3 varieties: Male, Female, and Albino (Male). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

Electric Blue Hap Habitat Setup

When setting up an aquarium for the Electric Blue Hap, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and smooth gravel or rounded substrate to protect their sensitive barbels.

Electric Blue Hap Compatibility Notes

Classified as aggressive, the Electric Blue Hap is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten, conspecific aggression can be intense, especially in smaller tanks, territorial behaviour may cause issues if hiding spots or floor space are limited, and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Electric Blue Hap Feeding & Diet Considerations

The Electric Blue Hap is a predatory species that will readily consume small fish, so nano or bite-sized tankmates should be avoided and will eat fry, so breeding efforts in the same tank are unlikely to succeed.

Fish Similar to Electric Blue Hap

Electric Blue Johannii

Pseudotropheus johannii

Cichlids - African
10 cm Aggressive

An iconic Mbuna cichlid from Lake Malawi renowned for extreme sexual dimorphism. Males transform into a striking electric blue with dark navy horizontal stripes, while females and juveniles remain a vibrant yellow-orange. Like most Mbuna, they are highly aggressive, territorial, and require hard, alkaline water with extensive rockwork to form caves. They are avid diggers and will destroy most live plants.

Yellow Lab (Mbuna)

Labidochromis caeruleus

Cichlids - African
10 cm Semi-Aggressive

The Electric Yellow Lab is one of the most popular and widely kept African Cichlids from Lake Malawi. Classified as an Mbuna (rock-dwelling cichlid), they are famous for their vibrant yellow coloration and striking black dorsal stripes. While considered one of the most 'peaceful' Mbuna, they are still highly territorial cichlids that require hard, alkaline water, a sandy substrate for digging, and abundant rockwork to establish territories.

Blue Dolphin (Hap)

Cyrtocara moorii

Cichlids - African
25 cm Semi-Aggressive

A striking blue Lake Malawi Haplochromine cichlid famous for the pronounced nuchal hump (head bump) that develops in mature adults, resembling a dolphin. They are benthopelagic micro-predators that naturally follow digging fish in the wild to catch stirred-up morsels. While relatively peaceful for an African Cichlid, they grow very large and require extensive swimming space and hard, alkaline water.

Cobalt Blue Zebra

Metriaclima callainos

Cichlids - African
11 cm Aggressive

A striking and highly active Mbuna cichlid endemic to the rocky shores of Lake Malawi. Known for its brilliant, solid cobalt blue coloration (though white morphs exist). Like most Mbuna, they are highly territorial, rock-grazing herbivores. They require an alkaline environment, a sandy substrate for digging, and extensive rockwork to establish territories. To manage aggression, they are best kept either in heavily populated, mixed all-male Mbuna tanks or in species harems (1 male to 3+ females).

Azureus Cichlid

Copadichromis azureus

Cichlids - African
16 cm Semi-Aggressive

A stunning open-water 'Utaka' cichlid from Lake Malawi. Males develop a spectacular metallic blue coloration, making them popular centerpieces in African Cichlid tanks. Compared to rock-dwelling Mbuna, they are relatively peaceful open-water swimmers but still require ample swimming space and hard, alkaline water.

Peacock Cichlid (Aulonocara)

Aulonocara sp.

Cichlids - African
15 cm Semi-Aggressive

Endemic to Lake Malawi, Peacock Cichlids are highly sought after for the breathtaking colors of the males. They are benthivorous, using sensory pores on their jaws to hunt small invertebrates in the sand. While territorial, they are generally peaceful compared to their aggressive Mbuna cousins. They require hard, alkaline water and a sandy substrate to prevent gill damage while sifting.
