Breeding Neolamprologus leleupi (Lemon Cichlid)

Breeding the Lemon Cichlid (Neolamprologus leleupi): a bi-parental cave spawner from Lake Tanganyika that lays up to 150 eggs and gives extended brood care to its fry.

Overview

Neolamprologus leleupi, the Lemon Cichlid, is a slim cave-dwelling Lamprologine from Lake Tanganyika reaching a maximum of about 10 cm. It is a bi-parental cave spawner. Seriously Fish notes it is placid toward most tankmates but very aggressive toward conspecifics, so pairing requires care.

Sexing

External sexing is difficult; adult males tend to grow larger than females. Reliable pairs are best produced by rearing juveniles together and allowing a natural bond to form. Seriously Fish warns that simply buying an adult male and female does not guarantee a bond and often results in the female being harassed to death.

Conditioning

Maintain hard, alkaline water; Seriously Fish recommends a pH of 8.2-9.0 and a temperature of roughly 25-27 C (77-80 F) for breeding. A varied carnivorous diet brings adults into condition.

Breeding Setup

Use an aquarium of at least 75 cm (30 in) in length with sand and rock caves. The pair will often excavate their own cave, so loose rock arrangements that allow digging are useful.

Spawning Behavior & Trigger

The pair spawns very secretively in a cave they often excavate themselves. The female deposits up to 150 eggs on the wall or roof of the cave. A bonded pair in mature lake-type water will spawn readily within their territory.

Egg & Fry Care

Eggs hatch in 3-4 days and fry become free-swimming at 8-10 days, guarded by the parents during early brooding. Fry are large enough to take brine shrimp nauplii from birth. Brood care is extended, lasting until the fry reach about 2.5 cm (1 in); parents may spawn again while earlier fry remain, forming a nuclear family.

Common Challenges

Conspecific aggression is the main hurdle: forced pairings can be lethal to the female. A spacious, cave-rich tank and naturally formed pairs greatly improve success.
