Auratus Cichlid Care Guide: Beautiful and Brutally Aggressive
This auratus cichlid care guide provides an honest look at one of the most beautiful yet notoriously aggressive fish in the freshwater hobby. The auratus cichlid (Melanochromis auratus) is a Lake Malawi mbuna that captivates with its striking gold and black striping, but its ferocious temperament has ended many a community tank experiment. At Gensou Aquascaping at 5 Everton Park, we always ensure hobbyists understand what they are getting into before committing to this species.
Species Overview
The auratus cichlid is endemic to the rocky southern shoreline of Lake Malawi in East Africa. Females and juveniles display a bright golden-yellow body with bold black and white horizontal stripes, while dominant males undergo a dramatic colour reversal, turning dark brown to black with lighter blue-white striping. Adults reach approximately 10 to 12 centimetres. This species belongs to the mbuna group, rock-dwelling cichlids known for their territorial behaviour and algae-grazing feeding habits.
Tank Size and Aquascape
A minimum tank volume of 250 litres is essential for a group of auratus cichlids, and larger is always better with this species. The aquascape should replicate their rocky Lake Malawi habitat with abundant rock formations, caves and crevices. Stack rocks to create multiple hiding spots and territorial boundaries, ensuring each fish can claim its own space. Use a coral sand or aragonite substrate to help buffer the pH. Live plants are generally not recommended, as auratus cichlids will uproot or consume most species, though tough varieties like Anubias tied to rocks may survive.
Water Parameters
Lake Malawi cichlids require hard, alkaline water. Aim for a pH of 7.8 to 8.6, a GH of 10 to 20 dGH, and a temperature of 24 to 28 degrees Celsius. Singapore’s tap water is typically softer and more neutral than ideal, so you may need to add a Malawi buffer or use crushed coral in your filter to raise and stabilise the pH and hardness. Perform 25 to 30 per cent water changes weekly and ensure excellent filtration, as mbuna produce a significant bioload.
Managing Aggression
The auratus is widely regarded as one of the most aggressive mbuna species. Males in particular are relentlessly territorial and will harass, injure or kill tankmates if given the opportunity. The most effective strategy is overstocking, which distributes aggression across many targets and prevents any single fish from being bullied to death. Keep one male with multiple females in a ratio of at least one to four. Avoid housing auratus with peaceful or similarly coloured species. Suitable tankmates include other robust mbuna such as yellow labs, demasoni and kenyi, though constant monitoring is essential.
Diet and Feeding
In the wild, auratus cichlids are primarily herbivores that graze on aufwuchs, the biofilm of algae and microorganisms coating rocks. Offer a staple diet of high-quality spirulina-based cichlid pellets or flakes. Supplement with blanched vegetables such as zucchini, cucumber and peas. Avoid high-protein foods like bloodworms or beefheart, as these can cause a potentially fatal condition called Malawi bloat. Feed two to three small meals daily rather than one large feeding.
Health and Disease Prevention
Malawi bloat is the primary health concern with auratus cichlids and mbuna in general. Symptoms include swelling, loss of appetite, rapid breathing and white or stringy faeces. It is often linked to improper diet, stress or poor water quality. Prevention centres on feeding an appropriate herbivore diet, maintaining pristine water conditions and minimising stress through proper tank design. Ich can also occur during temperature fluctuations, so keep conditions stable. Quarantine all new additions for at least two weeks.
Breeding
Auratus cichlids are maternal mouthbrooders. After a brief courtship display, the female collects the fertilised eggs in her mouth and incubates them for approximately three weeks. During this time, she does not eat and may hide among the rocks. Fry are released fully formed and surprisingly large, capable of eating crushed flake food or baby brine shrimp immediately. Provide plenty of rockwork for fry to shelter in, as adults, including the mother, may prey on them once released.
Should You Keep Auratus Cichlids?
The auratus cichlid is not for everyone. It demands a dedicated mbuna setup, careful stocking choices and an owner who appreciates aggressive species dynamics. However, for those who enjoy the energy and drama of an African cichlid tank, few fish offer a more compelling combination of beauty and personality.
