Scientific classification |

Hemichromis is a
genus of
fish from the
family
Cichlidae, known in the aquarium trade as Jewel
cichlids. Jewel cichlids are native to
west Africa. Within west Africa Hemichromis
species are found in creeks, streams, rivers and lakes with
a variety of water qualities.
Jewel cichlids can reach lengths of 7-13 cm (6inch) in
some species brightly coloured. Brighter body colouration is
generally evident during breeding. Sexual dimorphism is
limited, though male jewel cichlids are typically more
brightly coloured and in some species have more pointed
anal, ventral and dorsal fins. Like most cichlids, jewel
cichlids have high developed brood care. Hemichromis species
typically form monogamous breeding pairs and the female spawns on a
flat surface such as a leaf or stone. Both parents guard the
eggs, and participate in fry raising.

Aquarium care
Jewel cichlids are neither suited to beginners, nor the
usual community tank. Several young specimens may be kept in
a spacious aquarium, with stones and wood for cover until a
pair forms prior to breeding. Their innate aggression makes
them good candidates for keeping in a monospecies aquarium.
Jewel cichlids are omnivorous and will eat both live
foods and fish flakes.
