The threadfin acara, also known as Heckel’s thread-finned acara, is a South American species of cichlid fish. It is the only member of the genus Acarichthys and is native to rivers in the Amazon and Essequibo basins in tropical South America, and has become established in southeastern Asia
The Threadfin Acara Cichlid (Acarichthys heckelii) is a favorite among many cichlid enthusiasts due to its generally peaceful disposition and vivid coloration as it matures. Adults have high amounts of iridescent blue-green and bright yellow markings along with red, orange, and violet highlights, especially in males. This Amazon native can often be kept in groups and/or community tank setups with many other species.
The Threadfin Acara Cichlid will thrive in an aquarium with a sandy substrate and plenty of refuge such as clay pots, driftwood, and rock formations. It typically will not eat ornamental plants, but it does like to do a fair amount of digging, so plants that attach to driftwood and rockwork are recommended. This cichlid is generally compatible with other peaceful fish too large to be considered prey. Territoriality is typically at its peak during spawning. Dwarf shrimp and other small, delicate invertebrates should not be kept with the Threadfin Acara Cichlid, but more durable, larger invertebrates such as snails could possibly make good tankmates in a large enough aquarium. If spawning is desired, tankmates of other species should be kept to a minimum or avoided altogether.
Feeding is simple for the unfussy Threadfin Acara Cichlid. High-quality dry, frozen, and live meaty foods will all be readily accepted. Supplemental vegetable matter is also required. Quality and variety are the keys to a diet that will ensure that this fish maintains optimal health and coloration.
