General Description: The Yellow Rainbow is endemic to the Lake Tebera basin of Papua New Guinea. A ray of sunshine in the hobby, mature male Yellow rainbows are overall yellow-gold in coloration with orange fins and a dark stripe that runs through the middle of their body. In this species, females also have some light yellow coloration but it is certainly less intense than that of males. The majority of specimens available for sale, however, are juvenile fishes and young males might just be starting to show signs of coloration. With patience and the proper environment, your male [and female] Yellow rainbows will shine in no time! A popular fish for the planted aquarium, rainbowfish are relatively peaceful but can intimidate slower or timid species with their activity level. Yellow rainbows would do best in a mixed sex group of 6 or more individuals; mixing of different rainbow species can also be done successfully. Males will show their best coloration in the presence of both females and other conspecific males. An adult Yellow rainbow can reach a size of approximately 3.5″. Note: Aquatics Unlimited recognizes the impact of the aquarium trade on certain wild fish populations. Therefore, all of our Yellow rainbows are sourced from aquaculture.
Diet Requirements: Yellow rainbows are omnivores and relatively unfussy when it comes to food. A diet made up of various high quality vegetable based and protein based flake foods or floating pellet foods are ideal, in addition to offering frozen foods such as bloodworms, brine shrimp and daphnia. Variety is the spice of life in order to maintain color, immune function and longevity of your fish.
Care Requirements: An established minimum 55 to 75 gallon aquarium is ideal for a group of Yellow rainbows. Given the activity level of this fish, the length of the aquarium is particularly important to consider. A tight fitting lid is highly suggested because some individuals are known to jump. Yellow rainbows are intolerable of nitrite or ammonia spikes, and therefore should not be added into a biologically immature aquarium. Weekly water changes are encouraged to keep water parameters up to standard for Yellow rainbows (Nitrates < 15 ppm), as they require clean water and will especially show dull coloration in deteriorating water parameters. Given their natural habitat, Yellow rainbows like generous water movement and a well oxygenated environment that may only be achieved by a larger filtration system. An ideal aquascape for rainbowfish is dense, tall live plants on one side of the aquarium with open swimming space on the other side. Other décor is of insignificance to rainbowfish considering they mainly exploit the middle or top regions of the aquarium. Yellow rainbows rarely conflict with tank mates, though males could flare up at each other to maintain their status in the pecking order. Barbs, danios, and larger tetras make excellent tank mates for Yellow rainbows. This rainbowfish will not do well in soft or acidic water conditions. Recommended water conditions, 76-82° F, KH 10-20, pH 7.0-8.0.
