Blue Zebra

Adults can reach approximately 13 cm in length. Their body is pale blue with barely noticeable dark vertical stripes. Sexual dimorphism in this species is weakly expressed. Males are generally slightly larger than females, have a more developed frontal part of the head, and characteristic yellow spots on the anal fin. This fish is outwardly very similar to one of the color forms of the Red Zebra cichlid, some varieties of which, despite the name, also have a blue coloration and are almost indistinguishable from the Blue Zebra.

This fish is endemic to Lake Nyasa (Malawi), which is located in the East African Rift Valley, on the borders of Mozambique, Malawi, and Tanzania. In its natural environment, the Blue Zebra prefers the northern coast, inhabiting among piles of stones and rocks.

This species is aggressive and territorial. In small aquariums (about 100 liters), males show intolerance towards each other and can attack other fish. In such conditions, harem keeping is recommended, where there are 3–4 females per male. In more spacious tanks (hundreds of liters), a diverse community can be created, including several representatives of Mbuna, Aulonocara, and Utaka.

For keeping 5-6 individuals, the optimal aquarium volume starts from 150 liters. For tank decoration, it is sufficient to use sandy substrate, as well as large stones and rock formations to create shelters in the form of crevices and grottoes. There is no need to place live plants, natural driftwood, and other elements characteristic of tropical aquariums. Such an “empty” environment fully corresponds to the natural habitat of this species. For long-term well-being, it is important to maintain a stable hydrochemical composition of the water with high pH and dGH values. Regular siphoning of the substrate will help prevent the accumulation of organic waste (food remnants, excrement). It is also recommended to change part of the water weekly with fresh water.

In its natural habitat, the Blue Zebra feeds on algae and small organisms, scraping them from the surfaces of stones and rocks. In a home aquarium, it is extremely important to provide a diet rich in plant components. Specialized foods for Mbuna cichlids will be an excellent choice for beginner aquarists, as they contain all the necessary elements for a balanced diet.

Favorable conditions for spawning include a water pH in the range of 8.2–8.5, a temperature of 25–27°C, and a protein-enriched diet. At the beginning of the breeding period, the male chooses a suitable spot on the bottom for the future clutch, usually a flat stone or similar surface. After choosing the spot, the courtship process begins, which can sometimes be overly aggressive. It is precisely to distribute the male's attention that harem keeping is recommended. The female, accepting the courtship, approaches the spawning site and lays several dozen eggs. After fertilization, she takes the eggs into her mouth, where they will incubate for about a month until the fry appear. It is important to have shelters that will protect the female during the incubation period from excessive male attention. If such places are not provided, there is a high risk that the female will release the eggs prematurely. Some breeders place females in separate tanks during this time. However, it should be remembered that a prolonged stay of the fish outside the colony can lead to the loss of her place in the hierarchy and subsequent attacks by conspecifics upon her return.

This fish is characterized by its hardiness and unpretentiousness. Health problems usually arise from injuries, poor nutrition, or being in an unsuitable aquatic environment (with low pH and dGH values). Eliminating these external causes positively affects the fish's well-being. If symptoms persist, medication may be required. More detailed information can be found in the section "Diseases of Aquarium Fish."

When choosing individuals, it is necessary to pay attention to their overall activity and the absence of damage on the body. Healthy fish show pronounced territoriality and react quickly to external stimuli. Avoid purchasing fish with signs of emaciation, sunken bellies, or damage to the scales, which may be traces of fights in an overcrowded aquarium.

• Make sure the coloration matches the stated color form, as the species can be represented by both blue and white individuals.
• Give preference to individuals from aquariums where water parameters close to those natural for Lake Malawi cichlids are maintained.
• Check the behavior of the fish in the store: dominant males often show aggression towards neighbors, which is normal, but fish constantly hiding in corners or near the surface may be depressed or sick.
