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).
这些鱼对于其他的种是强韧, 和平的与高度聪明。 他们是 microfeeders 而不是肉食性的。 在荒野中，他们时常停留在深水域中而且从不来到了表面觅食。 他们从不在中层水域中游泳但是是典型的岩石-居民。 冒险进入开放但是从不远离岩石表面。 繁殖于裂隙与洞穴。 (参考文献 6770) 一夫一妻的对是最常见的。 (参考文献 54944)
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
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。
