General Description: The Threadfin Rainbow, also referred to as the Featherfin Rainbow, is native to various regions in Indonesia, however all specimens available within the aquarium trade are commercially produced through aquaculture. Both male and female Threadfin rainbows have a tan body with a blue sheen, but males will develop extremely elaborate fins. These fins are used in both sparing behavior between males and to gain the attention of females during spawning. In most cases, juvenile specimens are typically offered and have yet to reach their impressive potential. Acquiring a mixed sex group of 8 or more individuals is recommended for their social behavior, as males will display their best in the presence of females and other conspecific males. An adult Threadfin rainbow can reach a size of approximately 1-3/4″.
Diet Requirements: In the wild Threadfin rainbows are omnivores. Consideration needs to be taken when selecting food sources given their very small mouths. A diet made up of various high quality vegetable based and protein based flake foods, floating micro pellet foods and bug bites are ideal, in addition to offering frozen foods such as bloodworms, micro worms, brine shrimp and daphnia. Variety is the spice of life in order to maintain color, immune function and longevity of your fish.
Care Requirements: A minimum 15 gallon aquarium is ideal for a group of Threadfin rainbows. While these fish are small, this size aquarium better provides a stable environment. This species should not be introduced into a biologically immature aquarium. Threadfin rainbows are very intolerable of nitrite or ammonia spikes, and will not endure deteriorating water parameters. Weekly water changes are encouraged to keep water parameters pristine (Nitrates < 15 ppm). Given the environments in which they come from, Threadfin rainbows like gentle water flow that may be best achieved by a sponge filter. The aquarium should be aquascaped with a darker substrate and dense vegetation (live plants are preferred). Threadfin rainbows would also benefit from some floating plants, as this better mimics their natural environment. Threadfin rainbows are extremely peaceful and rarely conflict with tank mates. Their timid nature, however, may make them not suitable for traditional community aquariums that have overly rambunctious or competitive species. Mix Threadfin rainbows with other peaceful nano fishes to provide them with security. This species are great with Neocaridina shrimps. Extra care should be taken acclimating Threadfin rainbows. Recommended water conditions, 72-76° F, KH 7-10, pH 6.0-8.0.
