Food and Feeding

The Blue-Eyed Tropheus (Tropheus brichardi) is a herbivorous cichlid that thrives on a diet rich in vegetable matter. A high-quality cichlid pellet or flake food should form the staple of their diet, supplemented with spirulina flakes to enhance their coloration and overall health. Occasional treats such as live or frozen brine shrimp and bloodworms can be offered, but these should be provided sparingly to prevent digestive issues, particularly bloat, which is a common problem among Tropheus species. Feeding small portions multiple times a day instead of large meals can help maintain their digestive health.

Origin and Natural Habitat

The Blue-Eyed Tropheus is endemic to Lake Tanganyika, Africa’s longest and second-deepest freshwater lake. This species is found in rocky shorelines, where it grazes on algae-covered surfaces. The clear, mineral-rich waters of Lake Tanganyika are characterized by stable pH levels and moderate to high hardness, conditions that should be replicated in the aquarium for optimal health.

Sexing

Sexing Tropheus brichardi can be challenging as males and females appear quite similar. However, dominant males tend to display brighter coloration, typically a greenish body with a subtle golden tinge. Subdominant males and females are generally duller in color. In a group setting, the most dominant male will exhibit the most vibrant hues as he asserts his territory.

Breeding

The Blue-Eyed Tropheus is a maternal mouthbrooder, meaning the female carries the fertilized eggs in her mouth until they hatch. The courtship ritual involves the male and female shimmying and circling each other before spawning. The female lays eggs, which she quickly collects in her mouth, where they remain for up to four weeks before hatching. Once the fry are released, they can be fed with newly hatched brine shrimp or Cyclops to promote healthy growth. A separate breeding tank with stable water conditions may improve fry survival rates.

Lifespan

Under optimal conditions, the lifespan of Tropheus brichardi ranges from 3 to 6 years, although some individuals may live longer with excellent care, proper diet, and a well-maintained environment.

Tank Setup and Compatibility

To replicate their natural habitat, it is essential to provide plenty of rock formations in the aquarium. These rocks should be arranged to create caves and crevices where fish can retreat and establish territories. Sand or fine gravel is recommended as a substrate, as these fish enjoy grazing on algae growing on surfaces.

Blue-Eyed Tropheus are known for their territorial behavior, especially towards smaller fish. It is best to keep them in species-only tanks or with other similar-sized Tanganyikan cichlids that can handle their aggressive tendencies. Keeping them in groups of at least 10 individuals helps distribute aggression and prevents a single fish from being overly harassed.

Water Parameters

• Temperature: 23 - 26 °C (73.4 - 78.8°F)
• pH Range: 7.0 - 8.5
• Water Hardness: 8 - 20°dGH (142.86 - 357.14 ppm)
• Filtration: A high-quality filtration system is essential to maintain pristine water conditions.

Short Description

The Blue-Eyed Tropheus gets its name from the distinctive blue hue that its eyes develop when kept in ideal water conditions. This visually striking species is best suited for experienced aquarists who can maintain stable water parameters and provide a diet rich in plant matter. Due to their aggressive nature, they should be housed with fish of similar size and temperament. With proper care, Tropheus brichardi makes a fascinating and rewarding addition to a Lake Tanganyika-themed aquarium.
