The Melanochromis johannii, also known as the Johanni Cichlid or Bluegray Mbuna, is a species of cichlid endemic to Lake Malawi in Africa. It has an elongated body shape and striking coloration, with males being more colorful than females. The base color is bright blue with dark vertical stripes and yellow fins. They are territorial and aggressive fish, so it is recommended to keep them in spacious aquariums with plenty of rocks and hiding places to establish their territory. In terms of feeding, they are omnivorous and consume a variety of foods, including algae, small invertebrates, and commercial foods in the form of pellets and flakes. During reproduction, males display courtship behavior and construct nests on flat surfaces. The female deposits the eggs in the nest, and the male fertilizes them. The male then guards and fans the eggs until they hatch, and the fry swim freely.

Reproduction in Melanochromis johannii is oviparous. During courtship, males exhibit colorful displays and construct nests on flat surfaces such as rocks or coconut shells. The female deposits the eggs in the nest, and the male fertilizes them. After fertilization, the male takes on the responsibility of guarding and fanning the eggs to maintain proper oxygenation. The eggs hatch in about a week, and the fry are guided by the male to feeding and sheltered areas. Providing hiding places and structures in the aquarium is recommended to protect the fry and ensure their survival.

Estos peces son ciclidos africanos del lago Malawi agresivos, por lo general pueden convivir con otros Mbunas agresivos si cuentan con espacio suficiente en el acuario, rocas y escondites donde puedan refugiarse de ser necesario.
Como a estos peces les gusta estar refugiados en diferentes ubicaciones del acuario ya sean en plantas, troncos, rocas etc, si otro pez intenta entrar donde está escondido podrían haber confrontaciones por ese refugio.
Fish can live together as long as the space is spacious enough to delimit a territory, otherwise there may be aggressions for competing for the territory.
They can coexist while they are similar in size or the size difference is not very abysmal, since as the fish grows it increases the chances of eating its partner that did not grow much.
They can coexist together if the aquarium they share is large and spacious enough for both species to feel good, as some fish may attack others to feel that they have little space and try to eliminate the competition.
