African cichlids are colourful, wonderfully interesting fish with complex behaviours and very diverse personalities, which are the reasons behind their popularity among aquarium enthusiasts. In fact, only advanced aquarium keepers maintain these fish because of their specific needs and tendency to be aggressive. This guide provides the essential information for successfully keeping these wonderful fish.
Understanding African Cichlid Diversity
The term “African cichlid” encompasses a wide range of species from several lakes, most notably Lake Malawi, Lake Tanganyika, and Lake Victoria. Each lake has unique water parameters and cichlid varieties with different dietary requirements, temperaments, and preferred habitats. Before getting any cichlids, research the specific species you are interested in to understand their individual needs. Key differences include:
Mbuna (Rock-dwelling)
Herbivorous cichlids from Lake Malawi, which are colourful, and territorial. They need to be fed primarily algae and other plant material.
Haps (Open-water/Predatory)
From Lake Malawi as well, these cichlids usually grow bigger than Mbuna, and they eat everything, from insects and crustaceans to even smaller fish.
Tanganyikan Cichlids
From Lake Tanganyika, these cichlids live in a wide range of niches and behave in a very different manner. Some are shell dwellers, while others are found in rocky caves or in open water. Their dietary needs vary widely.
Victorian Cichlids
From Lake Victoria, many species are now endangered in the wild. Many of these cichlids have specific requirements for water parameters and diet.
Setting Up Your African Cichlid Aquarium
Tank Size:
African cichlids are highly active and territorial fish, which means they require ample space to swim and establish their territories. For smaller species like Mbuna, a 40-gallon tank is the absolute minimum, but this is only suitable for very small groups. A 75-gallon tank or larger is highly recommended to provide enough room for swimming and to reduce aggression among tank mates.
Larger species, such as Haps or certain Tanganyikan cichlids, require even more space—think 125 gallons or more. The larger the tank, the better, as it allows for a more stable environment and reduces stress on the fish. Always consider the adult size of the cichlids you plan to keep and plan your tank size accordingly.
Filtration:
African cichlids are known for their high bioload, meaning they produce a significant amount of waste. This makes efficient filtration absolutely critical. Over-filtration is strongly recommended to maintain water quality and keep ammonia, nitrite, and nitrate levels in check. Canister filters are a popular choice because they offer powerful mechanical, chemical, and biological filtration.
Additionally, you may want to consider using a combination of filters, such as a canister filter paired with a sponge filter or hang-on-back filter, to ensure optimal water clarity and quality. Regular maintenance of your filtration system, including cleaning or replacing filter media, is essential to keep it functioning effectively.
Substrate:
The substrate you choose for your African cichlid tank is important for both aesthetic and practical reasons. Sand or fine gravel is ideal for most African cichlids, as it mimics their natural habitat and allows them to exhibit natural behaviors like sifting and digging. Sand is particularly beneficial for species like Tanganyikan shell dwellers, which burrow and interact with the substrate.
Avoid coarse or sharp gravel, as it can harm the fish or damage their delicate fins. If you’re keeping Mbuna, a darker substrate can help bring out their vibrant colors, while a lighter substrate may be more suitable for species from Lake Tanganyika.
Decor:
Decor plays a crucial role in an African cichlid aquarium, as it helps create territories and hiding spots, which are essential for reducing aggression. For Mbuna, rockwork is particularly important. Use sturdy rocks like lava rock, slate, or Texas holey rock to build caves and crevices. Ensure the rocks are stable and securely stacked to prevent collapses, which could injure your fish or damage the tank.
Avoid sharp edges that could harm the cichlids. For Tanganyikan shell dwellers, such as Neolamprologus multifasciatus, provide plenty of empty snail shells (like escargot shells) for them to inhabit and breed in. Plants can be used sparingly, but be aware that many cichlids may uproot or nibble on them.
Water Parameters:
African cichlids thrive in hard, alkaline water, which replicates the conditions of their native lakes (Malawi, Tanganyika, and Victoria). The ideal pH for most African cichlids ranges from 7.8 to 8.6, and water hardness should be between 10-20 dGH. However, it’s important to research the specific requirements of the species you plan to keep, as some may have slightly different preferences.
Regular water changes (25-50% weekly) are essential to maintain water quality and remove excess nitrates. Use a reliable water test kit to monitor pH, ammonia, nitrite, nitrate, and hardness levels regularly. If your tap water is soft or acidic, you may need to use additives like crushed coral or cichlid salts to achieve the desired parameters.
Lighting:
While lighting is not as critical for African cichlid tanks as it is for planted aquariums, it still serves important purposes. Adequate lighting allows you to view and appreciate the vibrant colors of your cichlids, and it can also influence algae growth, which some cichlids may graze on. A standard aquarium light is usually sufficient, but you can opt for LED lights for energy efficiency and customisable brightness.
Avoid overly bright lighting, as it can stress the fish and encourage excessive algae growth. A lighting schedule of 8-10 hours per day is typically recommended to mimic a natural day-night cycle.
Diet and Feeding
Species-Specific Diet:
African cichlids have diverse dietary needs depending on their species and natural habitat. For example, Mbuna cichlids from Lake Malawi are primarily herbivorous and thrive on a diet rich in vegetable matter. In contrast, Haps (Haplochromis) and many Tanganyikan cichlids are omnivorous or carnivorous, requiring more protein in their diet. It’s crucial to research the specific dietary requirements of the cichlid species you keep to ensure they receive the proper nutrition. Feeding an inappropriate diet can lead to health issues such as bloating, malnutrition, or even aggression.
High-Quality Flakes and Pellets:
A staple of your cichlid’s diet should be high-quality, species-specific commercial foods. For Mbuna, look for spirulina-based flakes or pellets designed for herbivorous cichlids. For Haps and Tanganyikans, choose protein-rich formulas tailored to omnivorous or carnivorous cichlids. These foods are nutritionally balanced and often contain added vitamins and minerals to support your fish’s health. Always check the ingredient list to ensure the food meets your cichlid’s dietary needs.
Frozen and Live Foods:
While commercial foods form the basis of a healthy diet, frozen or live foods can be offered as occasional treats to provide variety and enrichment. Bloodworms, daphnia, brine shrimp, and mysis shrimp are excellent options for protein-loving cichlids. However, be cautious with herbivorous species like Mbuna—overfeeding protein-rich foods can lead to digestive issues such as Malawi bloat. Use these treats sparingly, no more than once or twice a week, and in small quantities.
Vegetable Matter:
For herbivorous cichlids like Mbuna, supplement their diet with fresh vegetables to mimic their natural grazing behavior. Blanched spinach, zucchini, cucumber, shelled peas, and spirulina sheets are excellent choices. These vegetables provide essential nutrients and fiber, promoting healthy digestion. Be sure to remove any uneaten vegetable matter after a few hours to prevent it from decomposing and affecting water quality.
Feeding Frequency:
African cichlids benefit from being fed small portions 2–3 times a day rather than one large meal. This mimics their natural feeding patterns and helps prevent overeating, which can lead to obesity and water quality issues. Only offer an amount of food that your cichlids can consume within 2–3 minutes. Overfeeding not only harms the fish but also increases waste production, leading to higher ammonia and nitrate levels in the tank. Consistency and moderation are key to maintaining a healthy feeding routine.
Compatibility and Aggression
African cichlids, although aggressive, especially Mbuna, are very compatible if stocked correctly. Research the temperament of your chosen species and plan your stocking accordingly.
- Overstocking: It might be a counterintuitive statement, but overstocking (within reason) can actually help diffuse aggression by reducing the establishment of individual territories. However, this requires very robust filtration.
- Mixing Species: Be careful when mixing species, especially those that look alike or have similar dietary requirements. Avoid mixing cichlids from different lakes unless you have a lot of experience.
- Observe and Adjust: Watch your cichlids closely for signs of aggression, such as chasing, nipping, or fin damage. Be prepared to adjust your stocking levels or rearrange the decor if necessary.
Disease Prevention and Treatment
- Quarantine: Quarantine new fish for a few weeks before introducing them to your main tank in order to not let disease spread. Maintain Water Quality: Good water quality is what will keep diseases away.
- Observe Your Fish: Regularly observe your fish for signs of illness, such as changes in behaviour, appetite, or appearance.
- Treatments: If your fish become ill, seek the advice of a reputable aquarium veterinarian or experienced aquarist for diagnosis and treatment options.
Conclusion
Keeping African cichlids can be a rewarding experience. By thoroughly researching your chosen species, providing a suitable environment, and maintaining good water quality, you can enjoy the beauty and fascinating behaviours of these remarkable fish for years to come. Remember, patience and observation are key to success with African cichlids.
