As in Melanochromis auratus, both male and female Melanochromis joanjohnsonae are very attractively (though differently) marked. Coloration also varies according to locality. Males have distinctive yellow egg-shaped markings on the anal fin as well as a wide black stripe running the length of the dorsal fin.
- Melanochromis exasperatus, Melanochromis textilis
- Native to Likoma Island near the east coast of Lake Malawi, but has been introduced around Thumbi West Island, located in the southwestern arm of the lake
- Males around 4in (10cm); females a little smaller.
- Territorial; males are intolerant of rivals.
- Wide range of commercial diets accepted, but livefoods preferred. Aquarium: Properly constructed backgrounds with plenty of boltholes. Must be well lit and well filtered. Medium-hard, neutral to alkaline water important. Temperature range: 72-79F (22 26C); slightly higher for breeding.
- Spawning may occur in the open, but eggs are often laid inside a cave and are incubated orally by female, who also protects the fry.
