The Threadfin Acara, also known as Heckel’s thread-finned acara, is a captivating species of cichlid fish native to the rivers of the Amazon and Essequibo basins in tropical South America. It holds the distinction of being the sole member of the genus Acarichthys and has also established populations in southeastern Asia.
Cichlid enthusiasts often favor the Threadfin Acara Cichlid (Acarichthys heckelii) for its peaceful demeanor and striking coloration, especially as it matures. Adult specimens showcase vibrant iridescent blue-green hues and bright yellow markings, complemented by red, orange, and violet highlights, particularly prominent in males. This Amazonian native is commonly housed in groups or community tank setups alongside various other species.
Thriving in an aquarium environment with sandy substrate and ample refuge such as clay pots, driftwood, and rock formations, the Threadfin Acara Cichlid generally does not consume ornamental plants. However, it exhibits a tendency to dig, making plants attached to driftwood and rockwork preferable. Compatible with other peaceful fish too large to be considered prey, territorial behavior typically peaks during spawning. It's advised to avoid keeping dwarf shrimp and delicate invertebrates with this species, although larger, more robust invertebrates like snails may fare well in sufficiently spacious tanks. For successful breeding, it's recommended to minimize or entirely avoid tankmates of other species.
Feeding the unfussy Threadfin Acara Cichlid is straightforward, with a preference for high-quality dry, frozen, and live meaty foods, supplemented with vegetable matter. A diverse and nutritious diet is crucial for maintaining optimal health and vibrant coloration.
