Overview
The green slender-tail hap is a large, fast Malawi predator for a very big tank. It is a fish for experienced keepers with the space and filtration to match its size.
Did you know
The green slender-tail hap's tapering tail is built for speed. Its slim, streamlined rear end lets this open water hunter accelerate onto smaller fish in the clear water off Malawi's coasts.
Caring for the green slender-tail hap
Give a green slender-tail hap a very big tank of at least 211 gal (800 L), with a long footprint for swimming. Lay a broad sand floor and keep the rockwork toward the back and sides rather than filling the tank. Leave open water above the sand.
Keep the water hard and alkaline, at 75 to 82°F (24 to 28°C) and a pH of 7.6 to 8.6. Strong filtration and generous tank length are the limiting factors for keeping it well. Feed meaty foods suited to a fish eater, such as quality pellets and frozen krill and mysis. Avoid a diet of live feeder fish.
Keep one male with a few females, but only alongside other large Malawi cichlids. Anything small enough to fit in its mouth will be eaten. It is too big and boisterous for a standard community.
Males flush metallic green as they mature. Like other haps, it is a maternal mouthbrooder, and the female incubates the eggs in her mouth. Breeding is rated as moderate.
