General Description: The Madagascar Rainbow has a limited natural range to clear streams of eastern Madagascar, an island off the coast of Africa. Unlike most other rainbowfish, Madagascar rainbows have a very elongated body shape. Adult male Madagascar rainbows will be light brown to tan with hues of iridescent green, yellow or blue with a dark line across the middle of the body and deep maroon colored fins outlined in black (except for the pectoral fins that are clear). Females will be plainer with less intensely colored fins that have no outline. 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 Madagascar 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. Madagascar 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 Madagascar rainbow can reach a size of approximately 3.5″ to 4.5″, with males averaging larger than females. Note: Aquatics Unlimited recognizes the impact of the aquarium trade on certain wild fish populations. Therefore, all of our Madagascar rainbows are sourced from aquaculture.
Diet Requirements: Madagascar 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 30 to 55 gallon aquarium is ideal for a group of Madagascar 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. Madagascar 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 Madagascar rainbows (Nitrates < 15 ppm), as they require clean water and will especially show dull coloration in deteriorating water parameters. Madagascar 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 decor is of insignificance to rainbowfish considering they mainly exploit the middle or top regions of the aquarium. Madagascar 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 Madagascar rainbows. Recommended water conditions, 72-78° F, KH 9-15, pH 4.5-7.5.
