Blue Acara: Care Guide for Beautiful Cichlid Species

You are about to embark on a journey deep into the vibrant world of the “Blue Acara”. This fascinating creature, known for its stunning blue scales and unique characteristics, has captured the attention of aquarists around the globe. As you delve into the intricacies of its appearance, behavior, and habitat, you will discover why the Blue Acara stands out among its aquatic counterparts. Prepare to be enchanted by the beauty and allure of this remarkable fish as we uncover the secrets behind the Blue Acara’s captivating presence.

Physical Characteristics


The Blue Acara, also known by its scientific name Andinoacara pulcher, gets its name from its stunning blue coloration, which is the most prominent feature of its physical appearance. The base color of the Blue Acara is a rich blue, ranging from light to dark shades, with a vibrant metallic sheen that adds to its beauty. The scales of this fish also exhibit a shimmering effect, further enhancing its overall appearance. In addition to their vibrant blue color, adult male Blue Acaras often develop a yellow or gold color on their dorsal fin and upper body, which contrasts beautifully with their blue hue. Females, on the other hand, tend to display less intense coloration, with a milder blue and less development of the yellow or gold accents.


Blue Acaras are a relatively medium-sized cichlid species. When fully grown, they can reach a size of about 6 to 7 inches (15 to 18 centimeters). The size difference between males and females is not significant, with males being slightly larger overall. However, it is important to note that the growth rate and final size of Blue Acaras can be influenced by factors such as diet, genetics, and tank conditions.


The Blue Acara has an oval-shaped body, typical of many cichlid species. Their bodies are laterally compressed, meaning they are flattened from side to side. This body shape allows them to navigate and maneuver easily through their aquatic environment. The Blue Acara also has a relatively deep body compared to some other cichlids. Their dorsal and anal fins are elongated, adding to their overall graceful appearance.


In addition to their stunning blue coloration, Blue Acaras showcase unique markings that further enhance their visual appeal. One distinguishing feature is the presence of dark vertical bars on their bodies. These bars tend to be more pronounced in juveniles and can fade or become less visible as the Blue Acara matures. Another notable marking is a black spot situated towards the posterior part of the fish, just below the lateral line. This spot is commonly referred to as an eyespot or ocellus. It serves as a form of camouflage and defense mechanism.


Native Range

The Blue Acara is native to the freshwaters of Central and South America. It is commonly found in countries such as Guatemala, Honduras, Nicaragua, and Costa Rica. These regions are characterized by tropical climates and abundant water bodies, including rivers, streams, and lakes. In the wild, Blue Acaras inhabit various habitats, including slow-moving rivers, flooded forests, and areas with dense aquatic vegetation.

Preferred Environment

In order to thrive, Blue Acaras require an aquarium setup that mimics their natural environment as closely as possible. They prefer warm water temperatures ranging between 75 to 80°F (24 to 27°C). The pH level should ideally be maintained between 6.5 to 7.5, with a slightly acidic to neutral water condition. The water hardness should be moderate, around 8 to 15 dGH. It is important to note that these are general guidelines. Specific water parameters may vary depending on the individual preferences and needs of the fish.

Aquarium Setup

To create an ideal habitat for Blue Acaras, it is recommended to provide them with an aquarium that has a minimum capacity of 30 gallons (114 liters) for a pair or small group. The tank should be equipped with an efficient filtration system to maintain water quality, as well as a heater to regulate the temperature. Blue Acaras appreciate the presence of caves, rocks, and driftwood in their environment. This can serve as hiding spots and territorial boundaries. Dense planting with hardy aquatic plants, such as Java Fern or Amazon Swords, is beneficial for providing cover and creating a naturalistic setting. Adequate lighting should also be provided to simulate their natural day-night cycle.

Social Structure

Blue Acaras are generally peaceful and can be kept in a community tank with other peaceful fish species. However, they do display some territorial behavior, especially during breeding and spawning periods. It is therefore advisable to provide plenty of hiding spots and separate territories when housing multiple Blue Acaras. Keeping a pair or a small group of Blue Acaras in a spacious tank with plenty of visual barriers can help prevent aggression and minimize stress.

Feeding Habits

Blue Acaras are omnivorous and have a versatile diet in the wild. They primarily feed on small invertebrates, such as insects, crustaceans, and worms, as well as plant matter. In the aquarium setting, they readily accept a variety of foods. Their diet should consist of a mixture of high-quality pellets or flakes supplemented with frozen or live foods like bloodworms, brine shrimp, and small crustaceans. Offering a varied diet helps ensure they receive a balanced nutritional intake and promotes optimal health and coloration.

Breeding Behavior

During the breeding season, Blue Acaras exhibit fascinating courtship rituals. The male becomes more vibrant in color, particularly on the dorsal fin and upper body, while the female displays a darker blue coloration. The courtship often involves the male displaying to the female by flaring his fins and intensifying his colors. Once a pair has formed, they will choose a site to deposit and guard their eggs. Both parents actively participate in tending to and protecting the eggs. Blue Acaras are known to be attentive parents, guarding their fry fiercely and ensuring their survival.


While Blue Acaras are generally peaceful, aggression may occur during breeding or when territorial disputes arise. It is important to monitor the behavior of your Blue Acaras and provide adequate hiding spots and visual barriers to minimize any potential aggression. If aggression persists or escalates, it may be necessary to separate individuals to prevent harm to other tankmates.


Natural Diet

In their natural habitat, Blue Acaras have a varied diet consisting of small invertebrates like insects, worms, and crustaceans. They also consume plant matter, such as algae and submerged vegetation. This diverse diet allows them to obtain the necessary nutrients for their growth and overall health.

Feeding in Captivity

In captivity, Blue Acaras readily accept a variety of commercially available foods. A high-quality pellet or flake food formulated for cichlids can serve as the staple diet. However, it is important to supplement their diet with additional protein-rich foods to ensure a well-rounded nutritional intake. Offering frozen or live foods like bloodworms, brine shrimp, and daphnia will mimic their natural diet and help maintain their health and vibrancy.

Food Preferences

Blue Acaras, like many cichlids, can be opportunistic feeders and take advantage of various food sources. They appreciate a mix of protein-rich foods and plant matter. It is beneficial to offer a variety of food types, including pellets, flakes, frozen foods, and live foods. This diversity not only keeps them physically satisfied but also provides mental stimulation, as they engage in foraging behavior similar to their natural feeding habits.


Compatible Fish Species

Blue Acaras are generally peaceful and can be kept with a variety of community fish species, provided they are not overly aggressive or prone to fin nipping. Good tankmates for Blue Acaras include peaceful community fish like tetras, livebearers, corydoras catfish, and other non-aggressive cichlid species. It is important to avoid housing them with overly aggressive or territorial fish, as this can lead to stress and potential conflicts.

Breeding Process

Blue Acaras breeding in captivity can be a rewarding experience for fishkeepers. To initiate the breeding process, it is best to provide the fish with suitable conditions, including proper water parameters, ample hiding spots, and a nutritious diet. The male will begin courtship rituals, displaying vibrant colors and engaging in fin-flaring behaviors to attract a female. Once a pair has formed, they will select a suitable site to lay their eggs. The female will deposit the eggs, and the male will fertilize them immediately. Both parents will actively guard and fan the eggs, ensuring proper oxygenation and preventing fungus or bacteria growth. After a few days, the eggs will hatch, and the fry will be released.

Care for Fry

Blue Acaras are attentive parents and actively care for their fry. The parents will guide the young fry to suitable areas within the tank, protecting them from potential threats and providing them with food. Initially, the parents may lead the fry to feed on the slime coat produced by their bodies. As the fry grow, they will begin to accept finely crushed flakes or pellets, alongside their parent’s regurgitated food. Separate rearing tanks or the presence of suitable hiding spots within the main tank can help protect fry from being consumed by adult fish or other tankmates.
