Marlier’s Julie [A Comprehensive Guide]

Marlier's Julie

Marlier’s Julie, also known as Spotted Julie or Chequered Julie, is a type of cichlid fish found only in the northwestern part of Lake Tanganyika. It prefers rocky shorelines and deep waters.

Marlier’s Julies are strong and peaceful toward other species and are very smart. They are microfeeders and not meat-eaters.

In their natural habitat, these fish stay in deep water and don’t come to the surface for food. They mostly live among rocks and rarely swim in open water away from rock cover.

These fish breed in crevices and caves. Marlier’s Julie usually forms monogamous pairs when breeding.

Marlier’s Julie grows up to 5.1 inches (13.0 centimeters) long, with adult females growing larger than males.

Marlier’s Julie Reproduction

A study shows that Marlier’s Julie can be both monogamous and polyandrous. Sometimes, a female has two territories with a male in each.

This idea was first proposed by Yamagishi and Kohda in 1996. However, most commonly, this fish forms monogamous pairs.

Males protect the nest from predators, including both cichlid and non-cichlid attackers.
