Aquascape: Provide a rocky or plant-heavy setup with hiding spots and open spaces for swimming.
Substrate: Fine to medium gravel or sandy substrate, with some plants if desired.
Disease Prevention: Maintain clean water, quarantine new fish, and avoid overcrowding. Regular water changes help prevent common diseases.
Filtration: A strong filter is recommended to handle the waste of this active species. Good water movement is key.
Lighting: Moderate lighting, not too intense, as it’s not essential for the species but will help plants thrive if included.
Water Flow: Moderate to strong water flow, simulating its natural river habitat.
Hardiness: Fairly hardy, but sensitive to poor water quality and fluctuations in water parameters.
Acclimation: Slow acclimation is crucial to prevent shock, especially when introducing them to a new aquarium.
Expected Lifespan: 5-10 years in captivity with proper care.
Special Requirements: Provide plenty of hiding spaces and territory as they can be territorial and aggressive, especially when breeding.
Temperament and Behavior
Behavior: The African Jewelfish Cichlid (Hemichromis bimaculatus) is active, curious, and territorial. It enjoys exploring its environment and may claim specific areas of the tank.
Breeding: Known to be egg layers, they are highly protective of their eggs and fry. They usually require a secluded area for spawning.
Aggression: This species is quite aggressive, particularly during breeding. They can be territorial toward other fish, especially in smaller tanks.
Tankmates Compatibility: Best kept with other robust, non-aggressive species. Avoid small or peaceful tankmates, as they may be bullied.
Activity Level: High activity level. They are constantly moving around the tank, hunting for food and exploring.
Schooling or Shoaling Behavior: They do not exhibit schooling or shoaling behavior. They are solitary and prefer their own space, especially when territorial.
Plant Compatibility: They may uproot plants, so it’s better to use hardy plants or provide additional secure planting arrangements.
Diet and Nutrition
Dry Foods: High-quality cichlid pellets or flakes can be used as a staple. Ensure the food is nutrient-rich for their active metabolism.
Frozen Foods: Bloodworms, brine shrimp, and daphnia are excellent choices for variety and protein.
Live Foods: Live foods such as worms, small fish, and brine shrimp are highly favored and promote natural hunting behavior.
Vegetables: Occasionally offer blanched vegetables like spinach or zucchini, though they are primarily carnivorous.
Algae: They may nibble on algae, but it is not a primary food source. Algae wafers can be offered occasionally.
Feeding Schedule: Feed 2-3 times per day, offering only as much as they can consume in a few minutes to avoid overfeeding.
Supplemental Foods: Occasionally supplement their diet with high-protein treats such as shrimp or small fish to maintain optimal health and color.
Tank Parameters
Tank size: Minimum 30 gallons for one fish, larger tanks are recommended for multiple fish or to allow more territory.
Tank Length and Measurements: A long tank is preferable, around 36 inches (90 cm) in length, to provide ample swimming space.
Water Temperature: 75-82°F (24-28°C), stable temperature is important for their health.
pH (Acidity/Alkalinity): A slightly acidic to neutral pH of 6.5-7.5 is ideal.
KH (Carbonate Hardness): 4-10 dKH, moderate hardness levels help stabilize pH.
GH (General Hardness): 5-12 dGH, moderately hard water is best.
Hardiness: Fairly hardy, but they are sensitive to rapid water changes or poor water quality.
Nitrate (NO3) levels: Keep nitrate levels below 20 ppm for optimal health. Regular water changes help manage nitrate buildup.

The History, Popularity, and Natural Habitat
History: The African Jewelfish Cichlid (Hemichromis bimaculatus) originates from the West African region, specifically in countries like Senegal, Guinea, and Liberia. This species has been recognized by aquarium enthusiasts since the early 20th century. In its native habitat, the African Jewelfish Cichlid thrives in slow-moving rivers, streams, and ponds where the waters are often stained by decaying plant matter. These cichlids are part of the Hemichromis genus, which includes several closely related species known for their vibrant coloration and aggressive nature. Their bold and striking appearance, especially during breeding, made them a favorite in both naturalist studies and aquarium displays.
Popularity: The African Jewelfish Cichlid (Hemichromis bimaculatus) gained popularity in the aquarium hobby due to its eye-catching coloration and active nature. Aquarists appreciate the fish’s vibrant red and blue hues, particularly during the breeding season when their colors intensify. However, their aggressive temperament limits their popularity among beginners, as they require a careful selection of tank mates and space to thrive. Despite this, more experienced hobbyists enjoy keeping them in species-specific tanks or in aquariums with other strong-willed fish. Their reputation as a colorful and dynamic species has solidified their place in the hobby, though their aggressive tendencies are often highlighted in care guides.
Natural Habitat: In the wild, the African Jewelfish Cichlid (Hemichromis bimaculatus) is typically found in the slow-moving waters of West Africa, including rivers, streams, and floodplain lakes. These habitats are usually shallow, with plenty of submerged rocks, plants, and fallen wood, providing the fish with plenty of hiding spots and territories. The waters are often slightly acidic to neutral, with varying hardness depending on the region. These fish are adapted to warm waters, and their natural environment supports a diet of small fish, invertebrates, and plant matter. In their natural habitat, they are territorial, especially during breeding seasons, and display the same aggressive behaviors that make them such a fascinating yet challenging species for aquarists to keep.

Frequently Asked Questions
Livestock FAQ
What size tank do African Jewelfish Cichlids need?
The African Jewelfish Cichlid (Hemichromis bimaculatus) requires a minimum of a 30-gallon tank to thrive. However, a larger tank is recommended to provide them with enough space to swim freely and establish territories. Larger tanks also reduce aggression and help with water quality management.
Are African Jewelfish Cichlids good tank mates?
The African Jewelfish Cichlid can be quite aggressive, especially during breeding. It’s best to keep them with other robust, semi-aggressive fish. Avoid peaceful or small species, as they may be harassed. If you want to keep them with other fish, make sure the tank is large enough to create distinct territories.
How do I breed African Jewelfish Cichlids?
Breeding Hemichromis bimaculatus is relatively straightforward if you have a healthy pair. Provide them with a flat surface like a rock or piece of slate where they can lay their eggs. Keep the water temperature between 80-82°F (27-28°C), and ensure there’s plenty of hiding space for the fry once hatched. The parents are very protective and may become quite aggressive.
Can African Jewelfish Cichlids live with plants?
Hemichromis bimaculatus may uproot or damage plants, especially in smaller tanks where they can establish territories. Hardy plants like Anubias, Java Fern, and Cryptocoryne can withstand their occasional nibbling, but be prepared for some plants to get damaged.
How do I prevent diseases in African Jewelfish Cichlids?
Prevent disease by maintaining excellent water quality through regular water changes and proper filtration. Quarantine new fish before introducing them to your main tank, and be cautious about overfeeding, as uneaten food can lead to poor water quality. Keep an eye on your fish for signs of stress or illness and act quickly if you notice anything unusual.
