Description: The Salmon-red Rainbow has an elongated, laterally compressed body with two dorsal fins, where the second one is longer than the first. The anal fin runs from the mid-belly to the caudal penuncle. The caudal fin is forked. The head and the mouth are small. An example of clear sexual dimorphism and dichromatism: male has a higher back and fins and a luminous pink body, while the female has a more elongated, yellow-olive body with a gleaming golden-yellow scales and transparent fins. Only the dominant male in a tank will develop the characteristic bright red coloration.
Breeding is easy. Recommend water temperature is 24-26 °C. Use Java Moss as a bottom spawning medium. The parents should be conditioned with live foods and plant based foods. The eggs, which require 7-8 days to hatch, are tacky and initially as clear as glass. The eggs are ignored by the parents. The slow growing fry are immediately free-swimming and seek food directly below the surface. Feed them Rotifers and puliverized egg yolk. Do not feed the fry with Cyclops nauplii since these, after ecdysis, will attack the fry. The young require small, frequent water changes. The males begin to change to brighter color after reaching a length of 2 inches (5-7 cm).
