Scientific Name
Tyrannochromis macrostoma
Family
Cichlidae
Origin
Lake Malawi, Africa
Temperament
Mildly Aggressive
Maximum Size
14 inches
Minimum Tank Size
150 US gallons
Tank Setup
Provide a sandy substrate with some sizable rocks to act as cover. They produce a lot of waste, so good filtration is necessary.
Tank Region
Middle-bottom
Diet
They are carnivorous. They will accept cichlid pellets and live/frozen foods such as prawns, cockle, mussel, lancefish, etc.
Breeding
They are maternal mouthbrooders, however it is unknown if they have spawned in aquaria.
Compatibility
Keep several females per male and don't house multiple males in the same tank, unless the tank is very large. They are predatory, so don't keep them with fish under 5 inches in length because these will get eaten. They are peaceful with fish too large to eat and can be kept with other large haps, as long as they don't need a vegetarian diet.
Ease of Keeping
Challenging
Care
pH: 7.6-8.8, Temperature: 75-82 degrees Fahrenheit
