Description
General Information:
The Dimidiochromis strigatus, also known as the Sunset Hap, is a sleek, torpedo-shaped predator hailing from Lake Malawi. Recognised for its horizontal dark stripe running from snout to tail and its metallic blue-green sheen in dominant males, this fish is both elegant and assertive. It is a visually impressive species well-suited to larger aquariums with ample swimming space.

Water Quality:
This species thrives in alkaline, well-oxygenated water with consistent quality. A sandy substrate with scattered rocks for territorial zones is ideal. Strong filtration and regular water changes are essential due to their carnivorous diet and size.
Feeding:
As a carnivore, the Dimidiochromis strigatus requires a protein-rich diet of quality cichlid pellets, krill, shrimp, and occasional live or frozen foods. Avoid feeding mammalian meats to prevent digestive issues. Feed once or twice daily in appropriate portions to avoid overfeeding.
Tank Mates:
Due to its semi-aggressive and predatory nature, tank mates should be other robust and similarly sized Malawi cichlids. Avoid housing with small, slender fish that could be mistaken for prey. Provide visual barriers and open space to reduce aggression and allow natural territorial behaviour.
Sexing:
Males are larger and more vividly coloured, displaying a metallic turquoise body with a distinct dark stripe when dominant. Females are more subdued in colouration, often greyish-silver with the same stripe. Venting is the most reliable method for early sexing.
Breeding:
This species is a maternal mouthbrooder. Males establish territories and display to attract females, who then incubate the eggs in their mouths for up to three weeks. Fry can be raised on finely crushed flakes or baby brine shrimp once released.
Maximum Size and Longevity:
They can grow up to 25 cm and live for 8–10 years with proper care and tank conditions. Their size and temperament make them suitable only for spacious aquariums with experienced keepers.
Fun Fact:
Dimidiochromis strigatus uses ambush tactics in the wild, often hiding among plants or rocks and striking quickly at smaller fish—mirroring their name “Dimidiochromis,” meaning “divided colour,” for their stealthy, camouflaged body pattern.
