Malawi Blue Dolphin Care Guide
Are you the proud owner of a Malawi Blue Dolphin (Cyrtocara moorii) or considering adding this stunning fish to your aquarium collection? In this comprehensive care guide, we’ll cover everything you need to know about keeping these magnificent cichlids happy and healthy in your home aquarium. From their dietary preferences to tank requirements and breeding tips, we’ve got you covered.
Malawi Blue Dolphin Diet
What to Feed Your Malawi Blue Dolphin
Feeding your Malawi Blue Dolphin is a crucial aspect of their care. These omnivorous fish have specific dietary requirements that you should be aware of:
- Prefer Live or Frozen Prey: The foundation of their diet should consist of live or frozen prey such as daphnids, artemia, earthworms, shrimp, or mussels.
- Avoid “Red” Foods: Foods like bloodworms, beef heart, and red meat can lead to serious intestinal disorders and even death in these cichlids. Avoid them.
- Freeze-Dried Foods: While you can use freeze-dried foods designed for aquarium use, it should be occasional as it can harm their health in the long run.
- Stimulating Feeding: If your Malawi Blue Dolphin shares its aquarium with sand-filtering fish, bury dry food in the sand to encourage natural feeding behavior. It’s a fascinating activity for both your fish and you!
Malawi Blue Dolphin Behavior
Understanding Their Behavior
Malawi Blue Dolphins are known for their relatively calm demeanor, but there are important behavioral aspects to consider:
- Intra-Male Aggression: Males can become aggressive if they feel overcrowded, especially during the breeding season. The dominant male may even kill weaker males.
- Sociable Nature: These fish thrive in shoals and need the company of their own kind, even in captivity. Maintain a ratio of one male to two or three females for a harmonious group dynamic.
- Tank Size and Stress: Despite their size, Malawi Blue Dolphins can get stressed easily, so providing ample space is crucial. A tank size of at least 1000 liters (260 US Gallons) is recommended for larger groups.
- Bottom Dwellers: They tend to live near the bottom of the aquarium, so make sure to create an environment that suits their natural behavior.

Choosing Tankmates
Selecting suitable tankmates is vital for the well-being of your Malawi Blue Dolphin:
- Tank Size Matters: Due to their need for space, it’s advisable to have a dedicated aquarium for these cichlids. However, they can live in a community tank of at least 500 liters (132 US Gallons) if necessary.
- Lake Malawi Species: Ideal tankmates include other Lake Malawi species, particularly those of similar size and temperament, such as Lethrinops and Copadichromis.
- Avoid Smaller Fish: Smaller fish are at risk of being preyed upon, so steer clear of species like M’bunas that may disrupt the peace.
- Hybridization Risk: Be cautious about closely related species, as hybridization can occur and lead to unwanted genetic outcomes.
Breeding Malawi Blue Dolphins
Reproduction Tips
Breeding Malawi Blue Dolphins in captivity is possible with the right conditions:
- Group Setup: Maintain a small group with one male and two or three females, but be cautious as sexing them can be challenging. Sexual maturity is typically reached at around 12 to 14 cm (4.7 to 5.5 inches).
- Water Parameters: Keep the water temperature between 25-26°C (77-79°F) and maintain a pH level of 7.8-8 for successful spawning.
- Oral Incubation: These cichlids are oral incubators. The male will clear a small hole in his territory where the female will deposit eggs, which he later fertilizes. The female carries the eggs in her mouth for about three weeks.
- Fry Survival: To enhance fry survival, consider isolating the female after the first week of incubation. This can be done by setting up a glass wall in your main aquarium. The fry will be protected from potential predators in the main tank.
- Slow Growth: Malawi Blue Dolphin fry grow slowly, and it may take up to two years for them to reach their adult size. Their diet typically includes Artemia nauplii.

Creating the Ideal Environment
Setting up the right aquarium environment is essential for the well-being of your Malawi Blue Dolphins:
- Tank Size: Depending on the number of specimens, opt for a tank size of 500 liters (132 US Gallons) for a trio or at least 1000 liters (260 US Gallons) for a group with two males and five or six females.
- Décor: Use sandy substrate and arrange rock piles with open swimming spaces. These fish prefer swimming over hiding. Incorporate hardy plants like Anubias Gigantea for aesthetic purposes.
- Water Parameters: Maintain stable water conditions as they don’t vary much in Lake Malawi. Be mindful of nitrates and perform regular water changes to keep them in check.
