These fish are hardy, peaceful toward other species and highly intelligent. They are microfeeders and not carnivorous. In the wild, they often stay in deep water and never come to the surface to feed. They never swim in midwater but are typical rock-dwellers. Ventures into the open but never far from the rock cover. Breeds in crevices and caves (Ref. 6770). Monogamous pairs are most common (Ref. 54944).

The same study (Ref. 54894) claims that polyandry aside from monogamy is also demonstrated by this species because of some observations in the nesting area where a female occupies 2 territories each with a male. This idea of an expanded mating system for J. marlieri was initially suggested by Yamagishi and Kohda (1996). However, monogamous pairs are most common (Ref. 54944). Males guard the nest against attacks by cichlid and non-cichlid predators alike (Ref. 54944).
