The Demasoni Cichlid (Pseudotropheus demasoni) is a vibrant and captivating addition to freshwater aquariums, valued for its striking appearance and active behavior. The Demasoni Cichlid is a relatively new addition to the aquarium hobby, as it was introduced into the hobby trade around the mid 1990's. Its bright coloration, sharp lines of color contrast and relatively peaceful demenior made it a very popular species almost overnight.
Demasoni cichlids are one of the most common freshwater fish in the aquarium hobby and make a great addition to an African cichlid tank. These eye-catching fish are relatively easy to care for.
Natural Habitat
Native to Lake Malawi in Africa, Pseudotropheus demasoni is endemic to the rocky shorelines of the lake, where they inhabit crevices and caves. In its natural habitat, the Demasoni Cichlid is found in large schools that swim near and amongst rocky areas that provide them protection from larger species and plenty of plants and algae on which to graze.
Physical Characteristics
- Appearance: The Demasoni Cichlid is recognized for its striking coloration, featuring a deep blue or purple body adorned with vertical black stripes. The vivid contrast makes them one of the more popular choices among cichlid enthusiasts. Their body pattern features crips alternating dark or light blue stripes.
- Size: A full-grown Demasoni cichlid can reach up to 3 inches in length, making them a great option for smaller tanks. Grows to about 3-4 inches (7.5-10 cm) in length. It’s the only dwarf cichlid species that reaches 2 ½ to 3 inches (6.4-7.6 cm).
- Lifespan: With proper care, Pseudotropheus demasoni can live up to 8 years. Typically lives for 5-8 years with proper care.
Habitat Requirements
Demasoni cichlid tank size should be fairly large to keep the fish be happy and healthy.
- Tank Size: A minimum tank size of 55 gallons is recommended for a group of 10 or more. A minimum of 30 gallons is recommended for a small group; larger tanks are preferred to provide ample swimming space and territory establishment. While this species can be kept in smaller tanks ranging from 3 feet in length or 50 + gallons, ideally they should be kept in slightly larger aquariums where they can be kept in small groups of 5 or more specimens.
- Water Conditions:
- Temperature: 76-82°F (24-28°C). The temperature should be kept between 78-82°F.
- pH: 7.5-8.5 (alkaline). Demasoni cichlids prefer a pH of 7.5 to 8.5.
- Hardness: Hard water (10-20 dGH). Demasoni cichlids prefer a water hardness of 10 to 20 dGH.
- Aquascaping: Provide a well-structured aquarium with plenty of hiding spots using rocks, caves, and other decorations to mimic their natural habitat. Plenty of rocks are very important in providing this species with a natural environment within the aquarium in which they can live peacefully with their tank mates and thrive. An abundance of caves, rock niches and rocky ledges will give this species enough territory to satisfy its curious nature and allow it to coexist with other similarly sized species that are not as dominant. Open swimming spaces are also essential. These fish also need a sandy substrate, as they love to dig and forage for food.
Diet
Demason’s Cichlid (Pseudotropheus demasoni) requires a low-protein, herbivorous diet to maintain optimal health and prevent digestive issues. Demasoni cichlids are omnivores. However, they prefer plant based foods. Since they rarely hunt in the wild, thanks to their limited nature, they often feed on other small aquatic animals like shrimps and tiny fish.

- Primary Diet: Herbivorous; in the wild, they primarily graze on algae and plant matter.
- Supplemental Feeding: In captivity, offer high-quality cichlid pellets or flakes, along with blanched vegetables and spirulina. A staple diet of spirulina flakes, high-quality cichlid pellets, and vegetable-based sticks should be provided. Fresh vegetables such as zucchini, spinach, and lettuce can be offered as supplements.
- Feeding Frequency: Feed small portions 1-2 times a day for optimal health, ensuring any uneaten food is promptly removed to maintain water quality. If you are keeping them, refrain from feeding them foods that are high in protein such as beef hearts. It can promote illness and even death.
Compatibility
If you’re wondering whether Demasoni cichlids are aggressive, the answer is a definite yes. Demason’s Cichlid (Pseudotropheus demasoni) is a strikingly beautiful but highly aggressive Mbuna species from Lake Malawi. These fish can be quite territorial and fiercely defend their space against other fish. Due to their territorial nature, they are best suited for species-only tanks or carefully managed Mbuna communities.
- Temperament: Semi-aggressive; they can be territorial, especially during breeding. Demason’s Cichlid is highly territorial and aggressive, particularly toward its own species.
- Suitable Tank Mates: Best kept with other African cichlids of similar size and temperament, such as Mbuna species. It is best kept in a heavily stocked species-only tank to spread out aggression. A ratio of one male to multiple females will help reduce conflicts.
- Incompatibilities: Avoid keeping with larger, more aggressive species or small fish that may be stressed or harmed by the Demasoni. In an aquarium, they will target any fish that looks similar. Therefore, exercising caution when introducing new fish to a tank with Demasoni cichlids is important.
Generally, keeping a minimum of 12 Demasoni in a tank is best. It gives males plenty of tank mates to help spread out aggression. Providing ample space to swim and establish their territories also reduces the risk of aggression between individual males. However, if you want to create a larger school of Demasoni, you should aim for around 15 or more. It gives each fish enough space to swim and explore while providing them plenty of company. Therefore, if you’re looking to create a stunning school of colorful cichlids, the Demasoni is a perfect choice.
Care Level
- Difficulty: Moderate; requires stable water parameters and regular maintenance to thrive. Caring for Demasoni cichlids is relatively easy, but it’s not recommended for beginner aquarists.
- Health Monitoring: Monitor for signs of disease, especially stress-related issues and common parasites. Another essential care requirement is ensuring that your Demasoni cichlids don’t develop the Malawi Bloat. This usually occur when the fish isn’t properly taken care of, or the aquarium is not well maintained. Regular water changes and good filtration are essential for their overall health. A good filtration system is essential to keep the water clean and toxins-free. Demasoni cichlids need good filtration and regular water changes.
Breeding
Like many Mbuna cichlids, Demason’s Cichlid is a maternal mouthbrooder.
- Breeding in Captivity: Breeding is possible with suitable conditions; they are mouthbrooders. Demasoni cichlids will mate and spawn approximately every six weeks if well-fed. During this time, they go into hibernation.
- Spawning: The female will lay eggs on flat surfaces, and the male will fertilize them. Flat rocks serve as ideal spawning sites. Males become highly aggressive during spawning, so adequate rock structures should be provided to create spawning territories. After fertilization, the female holds the eggs in her mouth for 2-3 weeks before releasing free-swimming fry.
Sexing Pseudotropheus demasoni can be challenging, as both males and females display identical bright blue and black coloration with bold vertical stripes. The Demasoni cichlid size and weight of both genders of juvenile cichlids are the same, which makes it difficult to know their gender when they are young.
