Malawi Hawk
Aristochromis christyi
Cichlidae
About
The Malawi Hawk is a large, torpedo-shaped predatory haplochromine endemic to Lake Malawi, where it patrols the intermediate zones where rocky shores meet open sand. Its pointed head and long, laterally compressed jaws are the tools of an efficient ambush hunter that turns on its side to pluck small fish from between the rocks. Dominant males glow with iridescent blue and gold, while the species stays largely solitary and roams widely. Handsome and characterful, it demands a very large, hard-water aquarium and tankmates too big to be swallowed.
Care
Give this big predator a spacious hard, alkaline tank of at least 450 L (180 cm long) with a sandy floor and open rock piles. Keep it singly or as one male with a few females, and never pair it with fish small enough to eat.
Diet
Piscivorous ambush hunter that in aquaria takes carnivore pellets and frozen prawn, mussel, cockle and lancefish. House only with fish too large to swallow and avoid rich fatty foods.

Telling males from females
What works for this species, most reliable first.
- Extended finsStrong · from about 8 months, and later in a suppressed male
On many cichlids and killifish the male's dorsal and anal fins draw out into trailing points as he matures, while the female's stay rounded.
- VentingA hint only · only on a mature fish, easiest when she is in breeding condition
The method breeders use when the answer has to be right. Hold the fish upside down in a wet hand or soft net and look at the two openings ahead of the anal fin. The forward one is the anus; the one behind it is what you are reading.
- Adult sizeA hint only · only across animals of the same age
In many cichlids, catfish and loaches one sex simply grows larger — usually the male, though there are well-known reversals.
