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).
這些魚對於其他的種是強韌, 和平的與高度聰明。 他們是 microfeeders 而不是肉食性的。 在荒野中，他們時常停留在深水域中而且從不來到了表面覓食。 他們從不在中層水域中游泳但是是典型的岩石-居民。 冒險進入開放但是從不遠離岩石表面。 繁殖於裂隙與洞穴。 (參考文獻 6770) 一夫一妻的對是最常見的。 (參考文獻 54944)
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
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).非洲: 坦噶尼喀湖的在西北部部份的特有種。
