Origin

The Aequidens diadema, commonly known as Acara, originates from the freshwater river systems of South America. They are typically found in the slow-moving waters of Brazil, Colombia, Peru, and Venezuela. These regions provide the perfect environment with soft, slightly acidic waters, rich with plant life and driftwood, which offer natural hiding spots and feeding grounds. In their natural habitat, Acara thrive in warm, tropical conditions.

Food and Feeding

Acara are omnivores, requiring a balanced diet that includes both plant-based and protein-rich foods. High-quality flakes or cichlid pellets should form the base of their daily feeding regimen. To ensure optimal health and vibrant coloration, it is important to supplement their diet with live or frozen foods such as bloodworms, brine shrimp, and daphnia. These protein-rich foods will help maintain their energy levels and overall condition. Feeding them 2-3 times a day in small portions is ideal, as it mimics their natural grazing habits.

Sexing

Sexing Acaras can be done by observing their physical features. Males typically have longer, more pointed dorsal and anal fins. They also tend to display brighter and more vivid coloration, especially during breeding periods. Females, on the other hand, are generally smaller with rounder, more subdued coloring.

Breeding

Breeding Aequidens diadema in captivity is relatively straightforward if the right conditions are provided. They prefer flat surfaces such as stones or slate as spawning sites. During spawning, the female will lay between 200-300 eggs, which are then fertilized by the male. Both parents play a role in brood care, often taking the fertilized eggs into their mouths for protection. After about 8 days, the fry will hatch and become free-swimming. At this stage, they can be fed newly hatched brine shrimp or finely crushed flake food.

Lifespan

With proper care, Acara can live up to 10 years in a well-maintained aquarium. Providing stable water parameters and a nutritious diet is essential for ensuring a long, healthy life.

Short Description

Aequidens diadema, or Acara, is a peaceful cichlid species that can become moderately aggressive during breeding. They are best housed as pairs in a species-only tank to avoid territorial disputes, especially during spawning. Acara appreciate a tank setup that includes rocks, driftwood, and dense vegetation to mimic their natural habitat and provide necessary hiding spots. While they are generally easy to care for, maintaining water quality and providing an enriching environment are key to their well-being.
