You might have been admiring the electric blue acara, a standout cichlid known for its vivid hues and engaging personality. This tropical fish isn't just a pretty face—it’s also a hardy tank companion that’s perfect for both novice and seasoned fish enthusiasts looking to add some intrigue to their aquatic collection.

The Striking Allure: Appearance and Characteristics
Electric blue acaras are a captivating sight with their intense blue sheen, enhanced by orange-tipped dorsal fins. As they mature, they can reach a length of 5 to 6 inches (13 to 16 cm), boasting a compact and robust body structure. Notably, these fish do not exhibit clear sexual dimorphism, meaning males and females look quite similar, making it tricky to tell them apart before breeding.

Creating the Perfect Habitat
Setting up a serene yet stimulating aquarium environment is crucial for the wellbeing of these vibrant swimmers. A spacious tank of at least 50 gallons is recommended to give your electric blue acaras plenty of room to explore and establish territory. Sand substrates paired with driftwood make for ideal tank setups, while hardy plants like anubias or java ferns can withstand their gentle digging habits.
Keep tabs on water parameters, as these fish thrive in a temperature range of 72–86°F (22–30°C) with a pH between 6.5 and 8.0. Efficient biological filtration is essential, considering their sensitivity to water quality.

Social Creatures: Behavior and Compatibility
Despite the edge that comes with the cichlid name, electric blue acaras are generally peaceful, making them excellent community tank members. They coexist well with similarly sized South American cichlids like Severums and Geophagus but should be kept away from smaller fish that might become accidental snacks. For those exploring compatible tank mates, consider reviewing suggestions in this guide on top tank mates for electric blue rams, which includes species that can also pair well with acaras.
Remember, during spawning, their protective nature kicks into overdrive, possibly increasing aggression. To maintain harmony, provide breaking sights within the tank using plants and decorations.
Nourishing for Brilliance: Diet and Feeding
A diet that mirrors their dynamic coloring includes a mix of protein-rich foods. Electric blue acaras thrive on high-quality pellets, flakes, and meaty treats like bloodworms and brine shrimp. The key to maintaining their health and vibrant color lies in a varied diet, ensuring these omnivores receive balanced nutrition.
