The Electric Blue Jack Dempsey, or EBJD, is a bright blue colour variant of the Jack Dempsey fish. While it was initially believed to be a hybrid, it is now thought to be a natural colour mutation. The Electric Blue Jack Dempsey is typically more docile and smaller than the standard Jack Dempsey. They are also more expensive. Breeding them can be challenging as they heal more slowly, grow more slowly, and are very sensitive to nitrates. If you breed two Electric Blues together, the resulting fry are often too weak to survive. To breed Electric Blues, you should breed a male Electric Blue Jack Dempsey to a normal female Jack Dempsey. Their offspring will carry the blue gene and can be bred back with an EBJD, resulting in 30-50% EBJD.

Electric blue jack dempseys are sensitive to nitrates and heal slower, making breeding challenging
The Electric Blue Jack Dempsey Cichlid (Rocio octofasciata "Electric Blue"), also known as the Powder Blue Jack Dempsey, is a bright blue colour variant of its species. It is typically more docile and smaller than "wild colour" individuals of the species.
Breeding Electric Blue Jack Dempseys can be challenging due to their sensitivity to nitrates and slower healing capabilities. Firstly, it is important to note that breeding two Electric Blue Jack Dempseys together will result in offspring that are too weak to survive. Instead, a male Electric Blue Jack Dempsey should be bred with a normal female Jack Dempsey. This will result in offspring that carry the blue gene but will not exhibit the blue colouration. These offspring, known as "blue-gene" fish, can then be bred with Electric Blue Jack Dempseys to produce a mix of Electric Blue Jack Dempseys and blue-gene fish.
To ensure the health and well-being of Electric Blue Jack Dempseys, it is crucial to maintain proper water parameters and water quality. They are sensitive to poor water quality, and high levels of ammonia and nitrites can be harmful or even fatal. Regular water changes, at least 25-30% every two weeks, are necessary to maintain stable water chemistry and prevent the build-up of harmful substances. Additionally, investing in a high-quality filter is essential to remove physical and chemical impurities from the water. A canister or hang-on-back (HOB) filter with both mechanical and biological filtration capabilities is recommended.
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 require a minimum tank size of 45 gallons for a pair, and the water temperature should be maintained between 78-82°F (25-28°C). The pH level should be slightly acidic to neutral, ranging from 6.5 to 7.5, and water hardness should be moderately hard to hard, with a recommended hardness level of 10-15 dGH.
It is also important to provide a varied and nutritious diet to ensure optimal health and coloration. High-quality dry, frozen, and live meaty foods, along with supplemental vegetable matter, are recommended.

To breed, you'll need a male and female from separate family lines
To breed Electric Blue Jack Dempseys, it is recommended to source a male and female from separate family lines. This is because inbreeding can cause health issues in the offspring, and it is generally better to breed fish from unrelated family lines.
Electric Blue Jack Dempseys are a bright blue colour variant of the Jack Dempsey species. They are believed to be a natural colour mutation that was isolated and developed within the original species. This variant is rarer than the traditional Jack Dempsey and is native to Central America and the Atlantic Coast of Mexico.
Breeding Electric Blue Jack Dempseys can be challenging due to their slower growth rate and smaller size compared to regular Jack Dempseys. They are also more sensitive to nitrates and take longer to heal from injuries. It is important to note that breeding two Electric Blue Jack Dempseys together will result in weak offspring that may not survive. Therefore, it is recommended to breed a male Electric Blue Jack Dempsey with a normal female Jack Dempsey. This will result in offspring that carry the blue gene, but they may not exhibit the blue colouration. To produce Electric Blue offspring, the blue-gene fish need to be bred back to an Electric Blue Jack Dempsey, resulting in a mix of Electric Blue and blue-gene offspring.
When breeding Electric Blue Jack Dempseys, it is important to provide a suitable environment. They thrive in an aquarium with a sandy substrate and plenty of refuge, such as clay pots, driftwood, and rock formations. The breeding tank should be a few degrees warmer than the main aquarium, and frequent water changes are necessary to maintain optimal water conditions. The female will lay her eggs on decorations such as stones or plants in the breeding tank.

The breeding tank should be a few degrees warmer with decorations like stones or plants
The breeding tank should be a few degrees warmer than the main aquarium. It is recommended to perform 30% water changes every 3 days to maintain pristine water conditions. The breeding tank should also include decorations, such as stones or plants, which will be used by the female to lay her eggs. Plants that attach to driftwood and rockwork are recommended, as Electric Blue Jack Dempseys like to dig.
The Electric Blue Jack Dempsey Cichlid will thrive in an aquarium with a sandy substrate and plenty of refuge, such as clay pots, driftwood, and rock formations. It will not eat ornamental plants but will grow to a considerable size of up to 8 inches (20 cm), so most ornamental invertebrates will eventually be considered prey. If spawning is desired, tank mates of other species should be kept to a minimum or avoided altogether.
The Electric Blue Jack Dempsey is a stunning, bright blue variant of its species. It is named after boxer Jack Dempsey, and its face is said to resemble the fighter. This variant is rarer than the traditional Jack Dempsey fish, and its origins are controversial. It is typically less aggressive than the standard Jack Dempsey, although it can display aggressive behaviour.
The breeding tank should be a minimum of 45 gallons for a pair. The Electric Blue Jack Dempsey is carnivorous, and a variety of high-quality dry, frozen, and live meaty foods are necessary for optimal health and coloration. Some vegetable matter is also required.

The female will lay eggs and the male may display aggression
The Electric Blue Jack Dempsey, also known as the EBJD, is a bright blue colour variant of its species. It is relatively easy to breed these fish, but it requires some preparation. Firstly, it is important to find a male and female pair that come from two separate family lines. The male EBJD should be a mature Electric Blue Jack Dempsey, while the female should be a normal Jack Dempsey. This is because mating two blue Dempseys can produce frail offspring that are hard to raise.
Once you have your pair, you will need to set up a breeding tank. This tank should be a few degrees warmer than your main aquarium and have decorations such as stones or plants. These decorations will be used by the female to lay her eggs. It is important to monitor the behaviour of the male and female EBJD during the breeding process. If the male displays aggression towards the female, remove her from the breeding tank and try again in a few days.
The female EBJD will lay her eggs in the breeding tank. After the fry hatch, you should quickly separate the lighter-coloured fry, as these will be the EBJDs. It is important to note that the EBJD line is constantly improving, and each time an EBJD is bred with a regular JD, the genetic diversity of the breed increases.
The Electric Blue Jack Dempsey is a stunning fish that is sure to be a rewarding addition to your aquarium. With its bright blue colour and unique pattern, it is a standout in any tank.

The fry will be lighter in colour and will need to be separated
The Electric Blue Jack Dempsey (EBJD) is an almost unbelievably bright blue colour variant of its species. It is a rare fish, and its origins are controversial. Some believe it is a natural colour mutation, while others claim it was bred by an Argentinian breeder.
To breed Electric Blue Jack Dempseys, you must first obtain fish that carry the blue gene. This can be done by breeding a male blue Jack Dempsey to a normal female Jack Dempsey. The resulting offspring will carry the blue gene.
Once you have fish with the blue gene, you can begin the process of creating EBJDs. It is important to note that breeding two Electric Blues together will result in weak fry that may not survive. Instead, you should breed a male Electric Blue Jack Dempsey to a normal female Jack Dempsey.
The fry that hatch from these eggs will be lighter in colour and will need to be separated. These lighter-coloured fry are the EBJDs. They will start off as a pale gold colour and will gradually turn fully blue as they grow. It is important to separate them from the other fry to ensure their safety and give them the best chance of survival.
Separating the fry can be done by using a net to gently scoop them out of the tank and place them in a separate container. It is important to work quickly and carefully to avoid stressing the fish. The new container should have similar water conditions to the original tank, including temperature and pH levels. It should also be well-oxygenated and have hiding places for the fry, such as plants and rocks.
