The leleupi is a slender, vivid lemon-to-orange rock-dwelling cichlid from Lake Tanganyika, one of the lake's most striking solid-colored species. It is a territorial cave spawner best kept as a bonded pair in a structured rocky aquarium.

Part of the Cichlids
Cichlids are a large, behaviorally complex family of freshwater fish prized for color, intelligence, and elaborate parental care. They range from peaceful dwarfs to highly territorial Rift Lake and Central American species, and most demand stable water chemistry and thoughtful tankmate selection.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Rocky Tanganyikan setup
40 gal breeder / 150 L
Neolamprologus leleupi is a rock-dwelling Tanganyikan needing hard, alkaline water (pH 8.2–9.0, 24–27 °C), strong filtration, and a wall of caves. Pairs are aggressive — provide many retreats.

Recommended
Tanganyikan community
55–75 gal / 200–280 L
Longer footprint accommodates a bonded pair plus shell-dwellers or open-water Cyprichromis. Crushed coral substrate buffers pH; rock piles create vertical territories.

Ideal
Large Tanganyikan biotope
90 gal+ / 340 L+ biotope
Stacked stone biotope with multiple cichlid species occupying their own niches. Stable hard alkaline params, strong flow, and protein-light diet (no beef heart) keep leleupi colourful and long-lived.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg
Fish eggs are small, translucent spheres, often laid in clutches on plants, substrate, or in a nest — or carried/brooded by a parent in livebearing and mouth-brooding species. A dark eye spot and the curled embryo become visible inside as development progresses.

Fry
Newly hatched fry are tiny and semi-transparent, frequently still carrying a yolk sac that fuels them before they feed freely. They lack full fin structure and adult coloration, staying near cover until they can swim and forage on their own.

Juvenile
Juveniles look like miniature adults but with developing fins and muted or different markings; many species shift pattern and color as they mature. Growth is rapid at this stage given clean water and steady feeding.
Adult
Adults show the species' full size, finnage, and mature coloration, and are sexually mature. Many fish develop sex-specific differences in size, color, or fin shape, which can intensify during breeding.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.

Yellow vs. orange color forms
Wild populations range from bright lemon-yellow to deep orange depending on locality; line-bred aquarium strains emphasize the most intense orange or gold coloration.
Habitat & enclosure
A pair needs at least 110 L (30 gal) aquascaped as a rocky biotope with many crevices and caves where the fish can retreat and spawn. Provide deep rockwork with shaded recesses, as leleupi are secretive and like cover. Water parameters: temperature 24-27 C (75-81 F), pH 8.0-9.0, hardness very high (GH 12-20, KH 12-18). They inhabit the rocky, cave-riddled habitats of Lake Tanganyika.
Substrate
Fine aragonite or coral sand buffers the water hard and alkaline and suits the biotope; the fish spend most time among rocks rather than digging extensively. Build secure caves and overhangs on the base glass so structures resist any excavation around their bases.
Equipment & setup
Reliable filtration (canister or quality hang-on-back) to maintain low nitrate, a dependable heater, and moderate flow. A secure lid is important as startled fish may jump. Subdued to moderate lighting suits this shade-loving species and can deepen its coloration. No specialty equipment beyond a stable Tanganyikan hardwater system is needed.
Diet
A carnivore/invertebrate feeder that hunts small crustaceans and insect larvae among the rocks in the wild. Offer frozen mysis, brine shrimp, cyclops, and a good carnivore-leaning cichlid pellet. Some vegetable content is fine but keep protein moderate and portions small to avoid the bloat common in Tanganyikan cichlids.
Behavior & temperament
Territorial, especially around the breeding cave, and can be scrappy with conspecifics; a compatible bonded pair is the usual approach. Biparental cave spawners that deposit eggs on a cave ceiling and guard fry diligently. Pairing can be difficult and aggression between mismatched adults is common, so grow out a group and isolate a pair. Somewhat shy, darting to cover when startled; strictly an observation fish.
Health
Hardy when kept in stable hard alkaline water. Bloat from overfeeding rich foods is the chief diet-related risk, and pairing aggression or bullying can cause injury and stress. Coloration can fade with poor diet or stress, so a varied carotenoid-containing diet and good water quality help maintain the intense lemon-orange hue. Quarantine new fish and watch for ich.
Tips, DIY & hacks
Raise a group of juveniles to obtain a bonded pair, then remove extra fish once a pair claims a cave. Feed carotenoid-rich foods (cyclops, krill, color-enhancing pellets) to maintain the bright lemon-orange color. Provide plenty of caves and broken sightlines to reduce aggression. House with peaceful, differently-zoned Tanganyikans rather than other cave-spawning Neolamprologus.
