Overview
The Perrieri hap is a small predatory cichlid from Lake Victoria for a group tank with open water. It suits a keeper with a little experience.
Did you know
The Perrieri hap is a survivor from an emptied guild. Its genus once counted dozens of predatory species in Lake Victoria, but introduced Nile perch pushed many of them to the edge. Fish like this one are clinging on partly through aquarium keepers.
Caring for the Perrieri hap
Keep Perrieri haps as a group, typically one male with several females, which spreads his attention and keeps the peace. A group settles into 42 gal (160 L) or more, with open swimming space, a sand floor and rock piles. The rocks break up sightlines and offer retreats.
Keep the water hard and stable, as the great lake fishes prefer. Aim for 73 to 81°F (23 to 27°C) and a mildly alkaline pH of 7.0 to 8.5. Feed meaty foods such as frozen bloodworm, brine shrimp, mysis and a good cichlid pellet.
The Perrieri hap swims in open midwater, hunting small prey. It is mild toward tank mates too large to be eaten. Pair it with other calm Victorian species rather than tiny fish it might snap up.
Like other haplochromines, it is a mouthbrooder, and the female shelters the fertilized eggs and fry inside her mouth. Breeding is of moderate difficulty.
Good to know
The Perrieri hap, Prognathochromis perrieri, is a cichlid of the family Cichlidae. Its genus name describes its jutting lower jaw.
In the wild
The Perrieri hap comes from Lake Victoria in East Africa. There it once ranged over soft bottoms, hunting smaller fish and invertebrates.
