Species description

Care, breeding and tankmates

Fish profile

Temperament

Aggressive

The Blue Acara is considered one of the more peaceful medium-sized cichlids, making it suitable for community tanks. However, they can show mild territorial behavior, which intensifies significantly during breeding. Both parents will defend their spawning site vigorously against any intruders. Outside of reproduction, they generally exhibit a calm and inquisitive demeanor.

Diet

Omnivore

As opportunistic omnivores, Blue Acaras require a balanced diet consisting of both meaty foods and vegetable matter. High-quality cichlid pellets or flakes should serve as the staple diet, supplemented with live or frozen foods such as bloodworms, brine shrimp, and Mysis shrimp. They will also appreciate occasional offerings of earthworms or blanched vegetables like spinach. Providing a varied menu ensures they maintain vibrant coloration and good health.

Life expectancy

8-10 years

In captivity, the Blue Acara has a typical lifespan of 8 to 10 years when provided with high-quality care. Achieving their maximum lifespan requires maintaining stable water parameters, a stress-free environment, and a clean aquarium. Offering a varied, nutrient-rich diet also plays a critical role in supporting their immune system and preventing premature aging. Regular health checks and avoiding aggressive tankmates will further ensure they live a full, healthy life.

Sex ratio

ONE_TO_ONE

In a home aquarium, the Blue Acara is best kept in bonded monogamous pairs. Keeping them in a 1:1 male-to-female ratio is ideal to prevent aggression, particularly during the spawning season. If you are starting with juveniles, a small group of 5 to 6 individuals can be raised together until a compatible pair naturally forms. Once a pair is established, the remaining fish should be moved to separate tanks to avoid territorial conflicts.

Feeding frequency

Twice daily

It is recommended to feed adult Blue Acaras one or two times a day, offering only what they can consume within two to three minutes. Overfeeding should be strictly avoided as it leads to poor water quality and digestive issues. Juvenile fish are growing rapidly and benefit from smaller, more frequent meals, about three times daily. Fasting them for one day a week can also help regulate their digestive systems.

Bioload

Medium to High

The Blue Acara produces a moderate to high amount of biological waste due to its size and high-protein diet. An efficient filtration system, preferably a canister or strong hang-on-back filter, is essential to maintain low nitrate levels. Regular weekly water changes of 25% to 30% are highly recommended to prevent the buildup of toxins. Keeping the substrate clean is also vital since these fish frequently dig and stir up debris.

Flow

Strong

In their natural habitat, Blue Acaras are found in a variety of water flows, from still lakes to moderate river currents. In the aquarium, they prefer a gentle to moderate water flow that mimics their natural river basins. Strong currents should be avoided as they can exhaust the fish and make swimming difficult. Using spray bars or filter deflectors can help distribute the current evenly.

Jump risk

Yes

Although not notorious jumpers like surface-dwelling species, Blue Acaras are active, powerful fish that can easily leap out of the tank when startled or during mating chases. A tight-fitting lid or canopy is highly recommended to secure the aquarium. Ensuring there are plenty of hiding spaces like caves and driftwood will also reduce stress and lower the likelihood of jumping. Floating plants can provide additional security and cover.

Reproduction

Oviparous

Breeding the Blue Acara is relatively easy and frequently occurs in captivity. They are open substrate spawners that typically choose a flat rock, slate, or broad leaf to deposit their eggs. Both parents exhibit exemplary parental care, guarding the eggs and aggressively defending the fry. The eggs hatch in about 2 to 3 days, and the parents will move the fry to pre-dug pits until they are free-swimming.

Compatibility & tankmates

Community

Suitable tank mates include deep-bodied characins, larger tetras, robust catfish like Loricariids, and other peaceful, medium-sized cichlids. Very small fish or shrimp should be avoided, as they will likely be seen as prey and swallowed. During breeding, they will become highly protective, so keeping them with active, fast-swimming companions is best. Avoid housing them with highly aggressive cichlids that could bully them.

Tank level

Middle/Bottom

This species is primarily benthopelagic, meaning it spends most of its time in the middle and bottom layers of the aquarium. They enjoy exploring sandy substrates and searching for food near the tank floor. Providing caves, driftwood, and low-lying vegetation helps them feel secure in their preferred swimming zone. They will occasionally swim to the upper levels, especially during feeding times.
