Docimodus johnstonii(misspelling)

Docimodus johnstoni is a species of haplochromine cichlid. It is known from Lake Malawi, Lake Malombe, and the upper Shire River in Malawi, Mozambique, and Tanzania. [2] This species has unusual feeding habits: it is reported to feed on fins of clariid catfishes. [2] [3] The specific name honours the British explorer, botanist, linguist and Colonial administrator, Sir Henry Hamilton Johnston GCMG KCB (also known as Sir Harry Johnston) (12 June 1858 – 31 July 1927), who presented the type to the British Museum (Natural History).

<i>Docimodus</i> Genus of fishes

Docimodus is a small genus of cichlids native to east Africa where they are found in Lake Malawi and one species (D. johnstoni) also occurs in Lake Malombe and the upper Shire River.

The Chitande aulonocara is a species of haplochromine cichlid which is endemic to Lake Malawi, only occurring in the north-west of the Lake near Chitande Island. It occurs over habitats of mixed rock and sand and it feeds on benthic invertebrates. The males show territorial behaviour all year and defend their territories from other males. These territorial males are found in deeper areas around 15 metres (49 ft) while the non territorial males and the females are rarely seen below 3 metres (9.8 ft). Ripe females descend towards the males and spawning takes place in a cavity or, if the male's territory does not include a cavity, on the open sand. The specific name honours the British ichthyologist Ethelwynn Trewavas (1900–1993) of the British Museum who described a number of species of cichlid from Lake Malawi.

Aulonocara guentheri is a species of haplochromine cichlid endemic to Lake Malawi, where they are restricted to the south eastern arm, and Lake Malombe, meaning that as far as is known this fish is endemic to Malawi. It prefers shallow sandy habitat where it forages in small schools, males in breeding colours have been caught by fishermen in November and December suggesting that is when they breed. The specific name honours the German born British herpetologist and ichthyologist Albert Günther (1830-1914), who was one of the first scientists to recognise the diversity of te cichlids in Lake Malawi.

<i>Diplotaxodon limnothrissa</i> Species of fish

Diplotaxodon limnothrissa is a species of haplochromine cichlid which is endemic to Lake Malawi and it is found in Malawi, Mozambique, and Tanzania.

It is probably the most abundant species of cichlid in Lake Malawi. The specific name references the clupeid Limnothrissa miodon, the Lake Tanganyika sardine, to which this species bears some morphological and biological similarities.
