Offered here at around \u003cstrong\u003e3-4 cm\u003c\/strong\u003e, these juveniles are still developing their adult patterning, making them an exciting choice for aquarists who enjoy watching cichlids mature. As with many mbuna, this species is best kept in a carefully planned aquarium with rockwork, stable water conditions and suitable tank mates.\u003c\/p\u003e\u003cp\u003eAdult males develop the species’ famous dark-and-light banding and can become highly territorial, while females and juveniles are usually less intense in colour. This is a fish for hobbyists who appreciate the character of Malawi cichlids and are prepared to provide the right environment.

In the wild, mbuna species inhabit rocky shorelines where they graze on algae and small associated organisms from the rock surfaces. The name “mbuna” is often used for these rock-dwelling cichlids, and it describes both their habitat and their energetic, territorial nature.\u003c\/p\u003e\u003cp\u003eThe Metangula form is associated with a specific locality and may show subtle differences in colour and pattern compared with other populations. Like other Lake Malawi cichlids, this species has evolved in mineral-rich, alkaline water with strong oxygenation and plenty of hiding places. Recreating these conditions in the aquarium is the key to long-term success.\u003c\/p\u003e\u003ch2\u003eTank Setup \u0026amp; Water Parameters\u003c\/h2\u003e\u003cp\u003eAmbitious rockwork is essential for this species. Use piles of stable limestone, reef rock, slate or other cichlid-safe hardscape to create caves, crevices and broken lines of sight. This helps reduce aggression by allowing each fish to establish a territory. A sandy substrate is ideal, as mbuna like to sift and forage around the bottom of the tank.\u003c\/p\u003e\u003cp\u003eFor a group or mixed mbuna setup, we recommend a tank of at least \u003cstrong\u003e250 litres\u003c\/strong\u003e, with larger aquariums preferred if keeping multiple males or a busy community of Malawi cichlids. Strong filtration is important because these fish are active and produce a fair amount of waste. Aim for excellent water movement and high oxygenation, and carry out regular partial water changes to maintain pristine conditions.\u003c\/p\u003e\u003cp\u003eKeep water parameters stable and alkaline:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature:\u003c\/strong\u003e 24-28°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epH:\u003c\/strong\u003e 7.8-8.6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness:\u003c\/strong\u003e Moderate to hard\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eDecor should be practical rather than planted. Most soft aquarium plants are likely to be damaged, uprooted or eaten. If you want greenery, consider hardy species attached to rockwork, but many keepers opt for a rock-only Malawi display to suit the fish’s natural behaviour.\u003c\/p\u003e\u003ch2\u003eFeeding Guide\u003c\/h2\u003e\u003cp\u003eIn nature, \u003cem\u003eMelanochromis johani\u003c\/em\u003e grazes on algae and the tiny organisms living within it. In the aquarium, the diet should be based on high-quality \u003cstrong\u003espirulina-based flakes or pellets\u003c\/strong\u003e, vegetable-rich cichlid foods and occasional treats such as blanched spinach, courgette or peas. A varied diet helps maintain colour, condition and digestive health.\u003c\/p\u003e\u003cp\u003eAlthough some prepared cichlid foods contain protein, avoid overfeeding rich meaty foods such as bloodworm, beef heart or excessive high-protein pellets. Mbuna are prone to digestive issues if fed the wrong diet, so keep meals small and regular. Feed once or twice daily in amounts the fish can consume quickly.\u003c\/p\u003e\u003ch2\u003eTank Mates \/ Compatibility\u003c\/h2\u003e\u003cp\u003eThis is not a fish for peaceful community aquariums. \u003cem\u003eMelanochromis johani\u003c\/em\u003e is best kept with other robust Malawi cichlids that can handle its territorial nature. Good tank mates are usually other mbuna or similarly sized African cichlids with comparable water requirements and temperament. Overstocking can sometimes help spread aggression in larger Malawi setups, but only if filtration and maintenance are up to the task.\u003c\/p\u003e\u003cp\u003eChoose companions carefully and avoid species that are timid, slow-moving or likely to be bullied. Fish with long fins, delicate body shapes or very different water needs are poor matches. It is also wise to avoid keeping multiple similar-looking males in a small aquarium, as this can trigger persistent aggression.\u003c\/p\u003e\u003cp\u003eAs a general rule, provide plenty of rockwork, keep the group structure sensible and monitor behaviour closely after introduction. Juveniles may appear peaceful at first, but adult males can become highly territorial as they mature.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Tropical Fish Co\u003c\/h2\u003e\u003cp\u003eWhen you buy live fish online, quality, packing and dispatch matter.
