Turquoise Acara

Adult males reach 30 cm in length, with their distinctive features being elongated dorsal and anal fins, as well as a noticeable nuchal hump. In their natural environment, this hump develops only during the breeding season, but in aquarium conditions, it persists permanently. Females are significantly smaller and do not have such pronounced features. The fish's coloration is a turquoise hue, falling between blue and green, with numerous black spots on each scale. This pattern extends to the fins. The dorsal and caudal fins are adorned with an orange fringe.

The natural habitat of this fish extends across the northern regions of Peru and along the western coast of Ecuador. It is found in South America, inhabiting river deltas that flow into the ocean, as well as streams and small rivers winding down the gentle slopes of tropical forests. It can often be seen in coastal zones, and less frequently in open waters.

The Turquoise Acara is an aggressive territorial species that can attack not only other fish but also its own kind. In smaller aquariums, it is possible to keep only one adult specimen or an already formed pair (male/female). In larger tanks (over 600 L), it can coexist with large catfish, cichlids, or characins, but in such a case, the Turquoise Acara should be a single specimen. Otherwise, when the breeding season arrives and it finds a partner, it can be dangerous for other inhabitants.

For keeping a single Turquoise Acara, an aquarium volume of at least 300 L is necessary. For decor, a sandy substrate is preferred, supplemented with various snags and rock formations. Artificial, as well as floating, vegetation can also be used to give the aquarium an aesthetic look. Lighting should be subdued. It is important to note that the Turquoise Acara is not favorable to live plants: they are likely to be uprooted or severely damaged. All decor elements must be securely fixed so that such a large fish cannot overturn or destroy them. Although hydrochemical parameters (pH and dGH) can have a wide range of acceptable values, simplifying water preparation, maintaining high water quality can be a challenge due to the significant volume of organic waste (given the fish's size) and the absence of plants capable of partially purifying the water. Therefore, a powerful filtration system is an essential condition, supplemented by regular aquarium cleaning.

This species is omnivorous and does not have specific dietary requirements. It is recommended to use specialized foods developed for South American cichlids, as they contain all necessary trace elements. To enrich the diet, live or frozen foods such as earthworms, as well as finely chopped shrimp or mussel meat, can be included.

This species forms stable pairs that can last throughout the fish's life. The exact mechanism of partner selection in Acara is still unknown, and not all fish can successfully pair up. For example, introducing a female to an adult male often results in her demise. However, if fish grow together in a group of 6–10 individuals from a young age, by the time they reach sexual maturity, there is a chance of at least one pair forming. Ideal conditions for spawning include soft, slightly acidic water with a temperature not exceeding 24°C. The stimulus for the start of the breeding period is a single replacement of a significant portion of the water (30–50%) with slightly cooler water. Before laying eggs, the female chooses a suitable spot — this could be a depression in the substrate, a flat stone, or any other decor element. A single clutch can contain up to 400 eggs. After fertilization, the female stays near the eggs, while the male patrols the territory, guarding its boundaries from intruders. It is important to note that during this period, he becomes unusually combative and capable of eliminating a potential intruder. The incubation period lasts approximately 3–4 days, and after another week, the fry begin to swim freely, preferring to stay near the female, who continues to protect them. Parental care lasts for several weeks.

The main cause of most diseases in these fish is unsuitable keeping conditions and poor-quality nutrition. If initial symptoms are observed, it is first necessary to check water parameters and the concentration of dangerous substances such as ammonia, nitrites, and nitrates. If the indicators deviate from the norm, they should be brought back into order, and only then should treatment begin.

When purchasing, choose active specimens with clean scales and clear eyes. Avoid fish with signs of emaciation, sunken bellies, or fin damage, as these cichlids are prone to stress during transportation and poor keeping conditions. In the store, assess their behavior: a healthy fish shows curiosity and territoriality, whereas an apathetic state or constant attempts to hide may indicate hidden diseases. Given the high level of intraspecific aggression, it is recommended to acquire young specimens from the same group to make it easier to form a compatible pair later on.
