Only males possess the impressive, electric blue coloration, while females are dull grey, and generally similar to the females of Aulonocara species. All Sciaenochromis are piscivores (fish-eaters) and prey mainly upon the fry of mbuna and other haplochromine cichlids.

Species

There are currently four recognized species in this genus:[1]

In the aquarium

Like all cichlids from Lake Malawi, they are best maintained in hard, alkaline water. Sciaenochromis are best kept in tanks with volumes greater than 210 l (55 gal). This is an aggressive fish, and the minimum tank size of 210 litres is only acceptable with a trio of 1 male and 2 females. If you are planning on keeping more males, it is highly recommended to have a larger tank, 350 l/100 gal being the minimum. Males can also display aggression towards similarly-coloured fish of other species, for example Aulonocara or Placidochromis.
