The Sixbar Distichodus is a massive, highly active African river fish. While sold as brightly colored, tiger-striped juveniles, they grow into enormous grayish adults. They are infamous for consuming all aquatic vegetation and becoming intensely territorial toward conspecifics as they age. They require enormous aquariums and robust tank mates.

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

Standard (Adult)

The massive adult form. Their vivid orange coloration fades to a reddish-gray or completely gray hue. They are highly territorial towards other Distichodus and must generally be kept as solitary specimens within their species.

Sixbar Distichodus Care Guide Summary

The Sixbar Distichodus, scientifically known as Distichodus sexfasciatus, belongs to the Characins family group. Adults reach a maximum size of approximately 76 cm and have a compressed body shape with a fast 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 Sixbar Distichodus requires a freshwater only aquarium with a minimum volume of 1000 litres and a tank length of at least 200 cm. Water temperature should be maintained between 22°C and 26°C, with a pH range of 67.5 and a general hardness of 1020 dGH. A moderate water flow is preferred.

Due to its specialist needs, the Sixbar Distichodus 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.

Sixbar Distichodus Habitat Setup

When setting up an aquarium for the Sixbar Distichodus, 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, smooth gravel or rounded substrate to protect their sensitive barbels, and driftwood, which can serve as both a hiding place and a dietary supplement. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation.

Sixbar Distichodus Compatibility Notes

Classified as aggressive, the Sixbar Distichodus is best housed alone, as they do not tolerate others of their kind in confined spaces. When choosing tankmates, avoid housing with slow-moving or long-finned species that may become targets for fin nipping, conspecific aggression can be intense, especially in smaller tanks, 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 Sixbar Distichodus Is Actually For

Sixbar Distichodus is best for a fishkeeper who expects a species with attitude and plans the tank around that behavior 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 Sixbar Distichodus 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.

Frequently Asked Questions About Sixbar Distichodus

Fish Similar to Sixbar Distichodus

Barred Rainbowfish

Chilatherina fasciata

Rainbowfish
14 cm Peaceful

A robust, active, and highly colorful schooling fish native to the clear, fast-flowing streams of New Guinea. They are named for the distinctive vertical black bars on their lower flanks. As highly active swimmers that do best in hard, alkaline water, they require a spacious, long aquarium (minimum 4 feet) with strong oxygenation and plenty of open swimming space.

Banded Rainbowfish

Melanotaenia trifasciata

Rainbowfish
13 cm Peaceful

A large, robust, and highly active schooling fish native to Northern Australia. Famous for its intense geographic color variations (such as the red 'Goyder River' morph). They are peaceful but incredibly fast and vigorous swimmers, requiring long aquariums with plenty of open swimming space.

Tinfoil Barb

Barbonymus schwanenfeldii

Cyprinids
35 cm Mostly Peaceful

A large, active, and schooling riverine species that quickly outgrows standard aquariums. Known for their metallic silver scales and red fins. They are notoriously skittish, robust eaters, and will consume almost any live plant or small fish that fits in their mouths. A massive tank with strong filtration is strictly required.

Shortbarbel Pangasius

Pangasius micronemus

Catfish
100 cm Mostly Peaceful

A massive, highly active riverine catfish native to Southeast Asia. Like its cousin the Iridescent Shark, it is a nervous and skittish swimmer prone to panicking and injuring itself on tank glass. Due to its enormous adult size of up to 1 meter (39 inches), it is strictly suited for only the largest custom aquariums, indoor ponds, or public aquaria. It is an opportunistic predator that will consume any tank mate small enough to fit in its large mouth.

Debauwi Catfish (Three-Striped Glass Catfish)

Pareutropius buffei

Catfish
8 cm Peaceful

A highly active, diurnal schooling catfish native to West African rivers. Unlike most bottom-dwelling catfish, they continuously swim in the mid-to-upper water column. While often sold in the trade as 'P. debauwi', virtually all specimens are actually 'P. buffei' (distinguished by having three lateral stripes instead of one). They are peaceful, require highly oxygenated water with moderate flow, and absolutely must be kept in groups.

Silver Prochilodus

Semaprochilodus taeniurus

Characins
30 cm Mostly Peaceful

A large, active riverine species famous for its striking striped tail and ability to consume massive amounts of algae. Commonly kept as a 'cleanup crew' in monster fish setups (with Arowanas or large Cichlids). They are peaceful towards other species but highly intolerant of their own kind unless kept in large shoals to disperse aggression.
