The Angostura Cichlid, scientifically known as various synonyms including Cichlasoma breidohri, Paraneetroplus breidohri, Herichthys breidohri, Paratheraps breidohri, and Vieja breidhori, is a captivating species originating from Presa de las Angostura, Mexico's largest hydroelectric dam. In its natural habitat, this cichlid thrives in flowing waters and adjacent lakes with a substrate of rocks, silt, and mud.

To ensure the well-being of the Angostura Cichlid, replicate its natural environment in the aquarium. Provide hard water conditions and a soft sandy substrate. Create hiding places and visual barriers using large pieces of driftwood, rocks, and slate. While most aquatic plants are viewed as potential food, consider using plastic or silk varieties. Efficient filtration is essential due to their messy eating habits, but maintain gentle water movement. Regular, small water changes are crucial to prevent the build-up of pollutants.

The Angostura Cichlid exhibits typical territorial behavior. Aggression levels are influenced by aquarium size, and providing ample space for fishes to establish territories helps minimize conflicts. Keeping them in a good-sized group allows for natural mate selection. Males tend to grow faster than females, so selecting a diverse group of juveniles is advisable to avoid a bachelor group. Suitable tankmates include large armored catfish and robust barbs or characins that can tolerate harder water conditions.

These cichlids are primarily vegetarian. Provide a well-rounded diet that includes green flakes, Spirulina-based pellets or sticks, and algae wafers. Supplement their diet with occasional frozen or live foods to ensure nutritional variety. The combination of plant-based and protein-rich foods contributes to their overall health and vibrant coloration.

In conclusion, the Angostura Cichlid is a captivating addition to freshwater aquariums, requiring specific care to thrive. By replicating its natural habitat, providing sufficient space, and offering a balanced diet, enthusiasts can enjoy the unique behaviors and striking appearance of this Central American cichlid in a home aquarium setting.
