What You'll Learn
Electric Blue Johanni Cichlid size
The Electric Blue Johanni Cichlid (Melanochromis johannii) is a species of fish native to the shallow rocky areas of Lake Malawi, where they rarely venture into open water. They are one of the more aggressive African cichlids and are characterised by their blue coloration, faint horizontal stripes, and dark black fins in males, while females are a solid yellow-orange colour.
Given their natural habitat, electric blue johanni require a well-oxygenated aquarium with a network of rock caves and hiding places. They are indifferent to open swimming space. A sandy or fine substrate is preferred, and African cichlid-specific substrates or marine Aragonite substrate are great choices to buffer the pH and alkalinity to levels found in Lake Malawi. The recommended water temperature is 74-80° F, KH 10-25, and pH 7.5-8.5.
In terms of size, electric blue johanni cichlids can reach an adult size of approximately 4 to 5 inches (10-13 cm), with males typically being slightly larger. They require a minimum tank size of 55 gallons for a single fish or a pair, and more space is needed for multiple males.
Electric blue johanni cichlids are primarily herbivores and should be fed a diet high in vegetables and spirulina-based flake or pellet foods. They should avoid high-protein foods and beef heart, as these can disturb their digestive system. With proper care and nutrition, these cichlids can live for 7-10 years.

Electric Blue Hap size
The Electric Blue Hap (Sciaenochromis ahli) is a species of cichlid fish native to Lake Malawi. They are a popular choice for aquarium owners due to their vibrant blue coloration and hardiness. These cichlids are relatively easy to care for and can be kept by beginner aquarists.
In terms of size, Electric Blue Haps can reach a length of approximately 7.9 inches (20 cm) in captivity, with males typically being larger and more colourful than females. The females, on the other hand, are a drab grey in colour and slightly smaller in size. It's worth noting that these cichlids are semi-aggressive, and it is recommended to keep only one male per tank. However, if a large number of fish are kept in a spacious environment, it is possible to keep more than one male.
The Electric Blue Johanni Cichlid, also known as the Electric Blue Hap, has a slightly smaller size range. Adults of this species typically grow to a size of approximately 4 to 5 inches, with males averaging slightly larger. These cichlids are native to the shallow rocky areas of Lake Malawi and require a well-structured aquarium with hiding places and caves.
Another variant of the Electric Blue Cichlid is the Electric Blue Jack Dempsey (Rocio octofasciata "Electric Blue"). This variant is known for its bright blue colour and is believed to be a natural colour mutation within its species. The Electric Blue Jack Dempsey attains a smaller size compared to the "wild colour" individuals of its species, typically reaching up to 8 inches (20 cm) in length. This variant is also less aggressive and can be compatible with other peaceful and semi-aggressive fish.
Overall, the size of Electric Blue Haps can vary slightly depending on the specific variant, but they typically range from 4 to 8 inches (10-20 cm) in length, with males being larger than females. These cichlids are a stunning addition to any aquarium and can live for 7-10 years with proper care and stable water parameters.

Electric Blue Jack Dempsey Cichlid size
The Electric Blue Cichlid, also known as the Electric Blue Hap, is a species of fish native to Lake Malawi. They are popular among aquarium owners due to their vibrant blue coloration and hardiness. These cichlids typically grow to a size of 4 to 5 inches as adults, with males averaging slightly larger than females. However, some individuals may reach larger sizes, with reports of Electric Blue Cichlids ranging from 5 to 8 inches in length.
The Electric Blue Jack Dempsey Cichlid, specifically, is a colour variant of the species Rocio octofasciata. This variant is known for its bright blue coloration and is typically more docile than the "wild colour" individuals of the species. The Electric Blue Jack Dempsey Cichlid can attain a considerable size of up to 8 inches (20 cm) in length.
The size of the aquarium and water conditions are important factors in maintaining the health and size potential of these fish. For the Electric Blue Cichlid, a minimum tank size of 55 gallons or 200 litres is recommended for a single specimen or a pair. The water temperature should be maintained between 24°C to 28°C, and the pH should be in the range of 7.5 to 8.6.
The Electric Blue Jack Dempsey Cichlid thrives in an aquarium with a sandy substrate and plenty of refuge, such as clay pots, driftwood, and rock formations. They are less aggressive than their wild-coloured counterparts, but they do exhibit territorial behaviour, especially during spawning. It is important to provide them with ample space and hiding places to reduce aggression.
In terms of diet, the Electric Blue Cichlid is primarily herbivorous. High-quality vegetable-based foods, spirulina flakes, and sinking pellet foods are ideal for their nutritional needs. Frozen spirulina brine shrimp can be fed in moderation, while high-protein foods and beef heart should be avoided as they can disturb their digestive system.

Tank size requirements
Electric Blue Cichlids are native to Lake Malawi and are known for their bright blue colouration. They are a popular choice for aquarium owners due to their vibrant colour and hardiness. These cichlids are relatively easy to care for and can be kept in a variety of tank setups. However, it is important to provide them with the appropriate tank size and conditions to ensure their health and well-being.
The minimum tank size recommended for a single Electric Blue Cichlid is 55 gallons or 200 litres. These fish can reach an average size of 12-20 cm, with males typically larger than females, so a spacious tank is necessary to accommodate their growth. It is worth noting that some sources suggest that these cichlids can grow up to 8 inches (20 cm) in length, so a larger tank may be required if you plan to keep a mature or fully grown adult.
For a single Electric Blue Johanni Cichlid, an established minimum 55-gallon aquarium is ideal. If you plan to keep multiple cichlids, especially males, you will need a larger tank to provide sufficient space and reduce aggression. A crowded tank can lead to increased territorial behaviour and aggression, especially during spawning. Therefore, it is recommended to have a larger tank if you intend to keep a group of Electric Blue Cichlids or mix them with other species.
The shape of the tank is also important to consider. A rectangular tank with good length provides the necessary swimming space for these fish. In addition to the tank size, it is crucial to maintain stable water parameters, including water temperature and pH levels. Electric Blue Cichlids thrive in water temperatures between 24°C-28°C and a pH range of 7.8-8.6, mimicking the conditions of their natural habitat in Lake Malawi.
The tank setup should also include a network of rock caves and hiding places, as these fish prefer rocky substrates and structures. A sandy or fine substrate is recommended, and the aquarium should be well-oxygenated. African cichlid-specific substrates or marine Aragonite substrate can help buffer the pH and alkalinity to levels similar to those found in Lake Malawi.

Diet and nutrition
Electric blue cichlids are omnivores and will eat a wide variety of foods. In the wild, their diet consists of algae, crustaceans, and small insects. In captivity, their diet primarily consists of quality cichlid pellets, occasionally supplemented with frozen krill, mysis, or brine shrimp.
It is imperative to provide them with a well-balanced and varied diet to ensure their well-being and enhance their stunning blue hues. A regimented care schedule is required, with feeding taking place once or twice per day.
The correct diet will not only keep your electric blue cichlids healthy but will also intensify their blue coloration. This makes choosing high-quality, diverse nutrition imperative for their overall health and appearance.
In addition to their diet, it is important to maintain optimal water conditions and cleanliness. Weekly water changes of 20-25% of the tank volume are recommended to sustain the appropriate water conditions, freshness, and cleanliness. Regular water changes also help to prevent diseases such as Hole in the Head Disease, which is caused by poor water quality, stress, or nutritional deficiencies.
Furthermore, it is crucial to be mindful of possible health problems that electric blue cichlids may face. They can be susceptible to various diseases, including Ichthyophthirius Multifiliis (Ich) and bloat. Ich is a parasitic disease that can be treated by gradually raising the tank temperature and adding prescribed medication. Bloat is often the result of overfeeding or parasites. Therefore, it is important to provide a well-balanced diet and maintain a clean tank to support the health and well-being of your electric blue cichlids.
