The Electric  Blue Acara is a freshwater fish native to the slow flowing rivers and lakes of Central and South America. They are from the Cichlidae family , a well-known group among fishkeeping enthusiasts.
They are a relatively tolerant fish that has a peaceful temperament. It will rarely cause you any trouble and will get along with most fish just fine. The only time you need to worry about aggression, is during breeding time.
The Electric Blue Acara can live for a relatively long time, especially if you compare them to other freshwater fish. With good care and aquarium conditions, they can live up to 10 years. In the wild this number is closer to 20 years.
Like many other members of the Cichlidae family, the Neon Blue Acara has become a popular choice for many aquarists.
They are very curious fish – this can be seen by their love for digging in to the substrate. In the wild this is of very little concern but when it comes to the tank, your equipment may fall victim to their boundless interest.
Given their passion for burrowing, they will usually be found near the base or middle layer of the tank. Sometimes they may swim up to the surface, but that would only be on rare occasions.
The swimming behavior of these fish is a healthy mix of hiding and swimming around. You will see them swimming around as well as navigating through the bushes of plants in the tank.
Maternal care in this species deserves a special mention too. The female acts like most mammals and will bring food to give to the offspring. This is quite unusual for fish.
The appearance of these Electric Blue Acaras is truly electric. Their eccentric colour pattern and unusual shade gradient combination makes them stand out from other aquarium fish. Their body is predominantly light blue with scales forming a netted dark pattern across their skin. They often have white, black or yellowish spots on the sides. Towards their head, the blue gradually turns into dull gray or black. This uneven pattern usually just covers their head but sometimes reaches lower. Their fins are also blue but in addition have an orange edging. It has densely packed scales that form beautiful, easily distinguishable cascades. Their body is elongated and compressed on the sides. The thinnest part of their body is where the abdomen transitions into the tail (caudal fin). They have a single, large, merged dorsal fin. Their caudal fin is circular, and is bigger than their pelvic, pectoral or anal fins. Their eyes are large with a dark pupil, enclosed by a reddish or orange iris. They also protrude above their head, this is especially apparent if you look at them as the fish swims towards you.
As for their size, they are not large. They usually grow up to 17-18cm in length.
