Black Belt Cichlid Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Standard (Adult)
The standard adult form. Best kept as a solitary 'wet pet', a proven male/female pair, or in a heavily filtered, massive Central American cichlid community tank to spread out aggression.
Same care requirements as the base species
Also known as: Adult Black Belt, Full Size, Male, Female
Juvenile (Grow-out)
Often sold at 5-10cm. While they can temporarily be housed in a 55-gallon (200L) aquarium, they will grow fast and quickly outgrow it. They are slightly less aggressive at this stage but will still bully smaller tank mates.

Black Belt Cichlid Care Guide Summary
The Black Belt Cichlid, scientifically known as Vieja maculicauda, belongs to the Cichlids - Central American family group. Adults reach a maximum size of approximately 30 cm and have a compressed 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 extreme level of biological waste.
To thrive, the Black Belt Cichlid requires a brackish tolerant aquarium with a minimum volume of 450 litres and a tank length of at least 150 cm. Water temperature should be maintained between 24°C and 29°C, with a pH range of 7–8 and a general hardness of 8–20 dGH. A moderate water flow is preferred.
Due to its specialist needs, the Black Belt Cichlid is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Standard (Adult) and Juvenile (Grow-out). 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.
Black Belt Cichlid Habitat Setup
When setting up an aquarium for the Black Belt Cichlid, 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 driftwood, which can serve as both a hiding place and a dietary supplement. Keepers should note that expect substrate disturbance, so lightweight décor should be secured and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation.
Black Belt Cichlid Compatibility Notes
Classified as aggressive, the Black Belt Cichlid is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, conspecific aggression can be intense, especially in smaller tanks and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Fish Similar to Black Belt Cichlid
Green Terror
Andinoacara rivulatus
A large, incredibly colorful, and highly aggressive South American cichlid. Known for their striking metallic green/blue scales and vibrant orange or white tail margins. As their name suggests, they are highly territorial and require very careful tankmate selection, usually only coexisting with other large, robust cichlids or armored catfish in very large tanks.
Firemouth Cichlid
Thorichthys meeki
A popular Central American cichlid famous for the bright red coloration on its throat and belly, which it flares to intimidate rivals. They are earth-eaters, constantly sifting sand for food. While territorial, especially during breeding, they are relatively peaceful for a cichlid of their size compared to larger Central American counterparts.
Chocolate Cichlid
Hypselecara temporalis
A large, deep-bodied South American cichlid famous for its 'gentle giant' temperament. They undergo significant color changes as they mature, eventually displaying rich chocolate browns, greens, and vibrant reds. Though peaceful for their size, they are still cichlids and will consume any fish small enough to fit in their mouths.
Duboisi Cichlid (Tropheus)
Tropheus duboisi
An iconic Lake Tanganyika cichlid famous for its dramatic life-stage color change. Juveniles are jet black with brilliant white polka-dots, while adults develop a blue head and a distinctive yellow or white vertical band across a dark body. They are highly aggressive toward their own kind and must be kept in large colonies (10+) to disperse aggression. They are strict herbivores that require a specialized diet to avoid fatal digestive issues.
Banded Cichlid
Heros notatus
Often sold as the Spotted Severum, this large South American cichlid is prized for its disc-like shape and the striking spots and bands along its lower half. They are native to the blackwater Rio Negro basin. While generally considered 'gentle giants' in the cichlid world, they are opportunistic predators that will eat any fish small enough to fit in their mouths. They are also notorious for devouring live aquarium plants.
Checkerboard Cichlid
Dicrossus filamentosus
A striking, slender South American dwarf cichlid known for its distinct black checkerboard pattern along its flanks. Unlike many cichlids, they are exceptionally peaceful community fish. They are strict blackwater species, requiring very soft, acidic water, sand substrate, and leaf litter to thrive.
