The Electric Blue Acara is an unnaturally occurring hybrid of the Blue Acara (Andinoacara pulcher) and a number of other species. The result is a fish with a bright blue body and hints of green and gold.

Their fins are typically much larger than those of the Blue Acara, with a long and pointed dorsal fin that stands tall above the fish’s body. Their pelvic and anal fins are also much longer than those of the Blue Acara.

Sex Differences and Color Variations

Male and female Electric Blue Acaras can be distinguished by their coloration and fin shape. Males typically have larger and more pointed dorsal fins and may display brighter colors than females.

Females may have a yellow or orange margin on their dorsal, anal, and caudal fins, whereas males do not.


Aquarium Setup and Decorations

To keep an Electric Blue Acara healthy and happy, it’s important to provide ample open swimming space and a sandy substrate. They appreciate plenty of hiding places so decorations such as rocks, driftwood, and caves are welcome additions to an Electric Blue Acara’s environment.

It is best to avoid sharp or jagged decorations as they can harm the fish.

Plant Options and Tank Size

Anubias, java fern, and hornwort are all popular plant options for an Electric Blue Acara tank. These plants thrive in a low to medium lighting environment and don’t require a lot of maintenance.

It’s recommended to use a tank size of 40-55 gallons for a single Electric Blue Acara, with an additional 20 gallons for each additional fish. This size provides enough space for an Electric Blue Acara to swim freely and retreat to hiding places.

Water Parameters and Tank Maintenance

Electric Blue Acaras thrive in soft, acidic water, with a pH of around 6.0 to 7.0. It’s important to maintain consistent water conditions by performing weekly water changes of around 20% of the tank volume. A high-quality filtration system is also necessary to keep the water clean and healthy for the fish.

Filtration and Aeration

Electric Blue Acaras require a low to medium flow filtration system, such as a hang on back or canister filter. It’s essential to avoid any high water flow as it can stress out the fish.

Adequate aeration is also important to maintain healthy oxygen levels in the water.

Lighting and Substrate

Electric Blue Acaras appreciate a low to medium light environment, with a period of darkness each day. Using a sandy substrate is recommended as it mimics their natural environment and allows the fish to forage for food.

In conclusion, providing a well-maintained tank environment and a consistent diet is important for the health and happiness of an Electric Blue Acara. With proper care, the fish will thrive, and their vibrant blue coloration will add a striking beauty to any aquarium.

Food and Diet

Electric Blue Acaras are omnivores and require a diverse and high-quality diet to maintain optimum health. They should be fed a variety of live, freeze-dried, and pellet food.

Foods such as brine shrimp, bloodworms, and daphnia are great choices for protein-based diets, while spirulina flakes, algae wafers, and fresh vegetables provide necessary plant-based nutrition. It’s essential to avoid over-feeding the fish as it can lead to health problems such as obesity and digestive issues.

Electric Blue Acaras tend to be active feeders, so feedings should be divided into two small portions throughout the day.

Community Tank Mates

Electric Blue Acaras are relatively peaceful, making them great additions to community tanks. However, it’s important to select compatible species to avoid any aggressive behavior.

They generally do well with other non-aggressive cichlids of similar size, tetras, rasboras, and invertebrates like dwarf crayfish. It’s not recommended to house Electric Blue Acaras with fin-nipping fish or aggressive species such as Oscar fish or African cichlids.

One popular companion fish for Electric Blue Acaras is the Silver Dollar fish. These fish are peaceful and can grow to be around six inches in length, making them a great match for the Electric Blue Acara.

Angelfish are also a popular companion fish for Electric Blue Acaras. These fish are also peaceful and come in a variety of colors, adding a beautiful contrast to the blue and green hues of the Electric Blue Acara.

Invertebrates such as shrimp, snails, or crayfish, can coexist with Electric Blue Acaras, as long as they are not small enough to be considered prey. Dwarf crayfish are a great option as they are energetic and attractive, making them an excellent complement to the Electric Blue Acara.

It’s important to keep in mind that Electric Blue Acaras can be territorial, so it’s important to provide enough hiding spots for each fish in the tank. Ensuring that each fish has areas to retreat to when feeling threatened or stressed can minimize aggressive behavior and promote a harmonious tank environment.

In conclusion, while the Electric Blue Acara is a peaceful addition to any community tank, it’s important to select compatible species to ensure a happy and healthy fish population. Providing a varied and healthy diet is essential for their overall health and well-being.

Electric Blue Acaras are a monogamous species, mating for life, and exhibiting strong parental care towards their offspring.

Breeding Electric Blue Acaras can be an enjoyable and rewarding experience for aquarists, but it requires careful consideration and patience.

Finding a

Breeding Pair and Spawning Process

Sexing Electric Blue Acaras can be challenging as they do not exhibit any major physical differences between males and females. However, males tend to have longer and more pointed fins than females.

It is best to purchase a juvenile group of Electric Blue Acaras and allow them to pair off naturally as they mature. Pairing off tends to happen in a stress-free environment where the males and females are well-fed and comfortable.

Once a pair has formed, it’s important to provide them with a breeding tank with appropriate conditions. A breeding tank of 30-40 gallons with a pH of 6.5-7.5, a temperature of 78-82F, and plant cover is ideal for breeding Electric Blue Acaras.

The spawning process typically begins with the male preparing a breeding site and luring the female into it; the pair then engages in a series of courtship behavior. The female then lays 100-400 eggs, which the pair fertilizes.

After spawning, the parents take turns guarding and fanning the eggs to ensure they receive adequate oxygen and are free from disease. The eggs usually take around 3-4 days to hatch, and once they do, the fry receive the same high-quality care from their parents until they are old enough to fend for themselves.

Challenging Part and

Breeding Success

The most challenging part of breeding Electric Blue Acaras is choosing the right pair. It’s important to avoid pairing two aggressive males or two females as they can turn on each other and harm their offspring.

Additionally, males may exhibit aggressive behavior towards each other when attempting to establish dominance. It’s best to introduce the males to the breeding tank at different times or provide enough hiding places to prevent aggressive behavior.

Breeding success can be achieved by providing the optimal breeding environment and taking the necessary steps to ensure the parents feel comfortable and secure. The quality of food and water conditions can also affect breeding success.

It’s recommended to feed the parents a high-quality diet leading up to the breeding process to ensure they are in optimal health. In conclusion, breeding Electric Blue Acaras can be a challenging but rewarding experience for aquarists.

Careful consideration and patience must be taken to choose the right pair and provide the optimal breeding environment. If done correctly, Electric Blue Acaras will exhibit strong parental care towards their offspring and provide aquarists with a unique opportunity to witness the beauty of nature in their own aquarium.

In conclusion, the Electric Blue Acara is a beautiful and fascinating fish that requires proper care and attention to thrive in a home environment. This article covered various aspects of caring for Electric Blue Acaras, including their appearance, diet, tank conditions, companions, and breeding.

It’s important to provide optimal conditions, such as a suitable tank size, high-quality food, and compatible tank mates. Electric Blue Acaras also need a proper breeding tank, a pair of fish that exhibit a healthy bond without aggression, and attention to details to ensure healthy offspring.

With proper care, the Electric Blue Acara can be a valuable addition to any aquarium, providing endless hours of joy, and a stunning visual spectacle to enjoy.
