The Electric Blue Jack Dempsey (EBJD) is a stunning freshwater fish known for its vibrant blue coloration. It's a variant of the standard Jack Dempsey fish (Rocio octofasciata), but with a unique, electric blue hue. Here are some key details about the Electric Blue Jack Dempsey:

Appearance

• Color: The Electric Blue Jack Dempsey features an iridescent blue color that can range from light blue to a deep, almost metallic blue. This color makes them highly sought after in the aquarium trade.
• Size: They can grow up to 8 inches (20 cm) in length, although they are often smaller in home aquariums.
• Body Shape: They have a robust and laterally compressed body typical of cichlids, with large dorsal and anal fins.

Behavior and Temperament

• Temperament: While the standard Jack Dempsey is known for its aggressive behavior, the Electric Blue Jack Dempsey is generally more peaceful, making it somewhat easier to keep in a community tank.
• Territorial: They can still be territorial, especially during breeding, so providing ample space and hiding spots is important.

Habitat and Tank Requirements

• Tank Size: A minimum of 50 gallons is recommended for a single Electric Blue Jack Dempsey, with larger tanks needed for multiple individuals or a community setting.
• Water Conditions: They prefer slightly acidic to neutral water with a pH between 6.5 and 7.5, and temperatures ranging from 75°F to 80°F (24°C to 27°C).
• Tank Setup: Include plenty of hiding spots with rocks, caves, and plants, but also ensure there is open space for swimming.

Diet

• Omnivorous: Electric Blue Jack Dempseys are omnivorous and thrive on a varied diet that includes high-quality pellets or flakes, live or frozen foods such as brine shrimp, bloodworms, and occasionally fresh vegetables.

Compatibility

• Tank Mates: Due to their relatively peaceful nature, they can be kept with other similarly sized and temperament fish, such as other peaceful cichlids, larger tetras, and catfish. However, avoid very small fish or extremely aggressive species.

Care Tips

• Water Quality: Maintaining good water quality is crucial for their health. Regular water changes and a good filtration system are essential.
• Monitoring: Keep an eye on their behavior for any signs of stress or illness, and ensure they have adequate space to prevent territorial disputes.

The Electric Blue Jack Dempsey is a beautiful and unique addition to a properly managed aquarium, offering both vibrant colors and a generally manageable temperament compared to other cichlids.
