Red Fin Borleyi Varieties

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

Male

Mature males develop a spectacular metallic blue head, an orange/red body, and elongated pelvic fins. Highly territorial towards other males of the same species. Best kept as a single male alongside a harem of females.

Differs in 3 traits from base species

Also known as: Show Male, Colored Male, Kadango Red Fin

Female / Unsexed Juvenile

Females and juveniles are plain silver/grey, often with three faint dark spots on the flanks. They are much more peaceful than males and should be kept in a harem (3+ females per male) to disperse the male's breeding aggression.

Red Fin Borleyi Care Guide Summary

The Red Fin Borleyi, scientifically known as Copadichromis borleyi, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 16 cm and have a compressed body shape with a moderate growth rate. Classified as semi-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 Red Fin Borleyi requires a freshwater only aquarium with a minimum volume of 280 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 7.58.5 and a general hardness of 1025 dGH. A moderate water flow is preferred.

The Red Fin Borleyi is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Male and Female / Unsexed Juvenile. 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.

Red Fin Borleyi Habitat Setup

When setting up an aquarium for the Red Fin Borleyi, 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. Keepers should note that expect substrate disturbance, so lightweight décor should be secured.

Red Fin Borleyi Compatibility Notes

Classified as semi-aggressive, the Red Fin Borleyi is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, 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.

Who Red Fin Borleyi Is Actually For

Red Fin Borleyi is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.

The most common mistake is treating Red Fin Borleyi like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

Fish Similar to Red Fin Borleyi

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.

Red Empress

Protomelas taeniolatus

Cichlids - African
15 cm Semi-Aggressive

A stunning and relatively peaceful Lake Malawi Haplochromine cichlid. Males develop breathtaking red and blue coloration, while females remain a camouflaged silvery-brown. Though considered a 'gentle Hap' compared to Mbuna, they are still large, active African Cichlids that require hard, alkaline water, plenty of swimming space, and rockwork.

Fort Maguire Peacock

Aulonocara hansbaenschi

Cichlids - African
13 cm Semi-Aggressive

A stunning Lake Malawi Peacock cichlid known for the male's metallic blue body and vibrant red/orange flush behind the gills. Like all Aulonocara, they are benthivores (sand-sifters) that hunt small invertebrates using enlarged sensory pores on their lower jaw. They require hard, alkaline water and a fine sand substrate to exhibit natural behaviors without damaging their gills.

Butterfly Peacock Cichlid

Aulonocara jacobfreibergi

Cichlids - African
15 cm Semi-Aggressive

One of the most colorful and slightly more aggressive Peacock cichlids from Lake Malawi. They are obligate sand-sifters that search for benthic invertebrates. They require hard, alkaline water and plenty of rocky caves. Like most Aulonocara, they exhibit extreme sexual dimorphism.

Featherfin Cichlid

Cyathopharynx furcifer

Cichlids - African
21 cm Semi-Aggressive

A spectacular Lake Tanganyika cichlid known for its dramatic sexual dimorphism. Males display brilliant metallic hues (blues, greens, or coppers depending on collection point) and possess sweeping, elongated pelvic 'feather' fins. Males build enormous crater-like sand bowers to attract females. Because of this bower-building behavior and their high activity level, footprint (length and width) is far more critical than tank height.

Maison Reef Peacock

Aulonocara stuartgranti "Maison Reef"

Cichlids - African
13 cm Semi-Aggressive

A stunning African Cichlid from Lake Malawi's intermediate zones (sand/rock transitions). They are 'benthophagous' sand-sifters, requiring fine sand to hunt for invertebrates without damaging their gills. Like most Peacocks, they are highly sexually dimorphic and require hard, alkaline water (Rift Lake parameters).
