Description
The Altum Angelfish is a majestic freshwater cichlid known for its exceptionally tall body and elongated fins, making it one of the most striking aquarium fish. Originating from the Orinoco and upper Rio Negro basins, it requires very specific soft, acidic water conditions and a tall tank to thrive. This species is often wild-caught and considered an expert-level fish due to its demanding care requirements.
