Description: The Yellow Congo Tetra remains slightly smaller than it's cousin, and is also somewhat more delicate. An exceptionally attractive Tetra with a similar body shape to the more commonly seen Congo Tetra. Their body is pale but exhibits iridescence under the right lighting conditions. The dorsal part can show blue reflections while the sides of the body reflect light with hues of yellow and silver. Their caudal fin is elongated and striking yellow in colour giving them their common name. All other fins are translucent with luminous blue-white edging. Keep a group of five or more to prevent fish from becoming timid. The fish is not a plant-eater.

Pelvic fins are tripped with white on male and are clearer on female. Females also lack the black extended middle section of the caudal fin. The hardest thing to breed the Yellow Congo Tetra is to get the females in proper breeding condition, which is mainly depending on a varied diet. Frequently feeding the breeding pair with flies, and other insects is sometimes the key to a succesfull breeding attempt. A large breeding tank, 80 cm, sunny location, lowered waterlevel, and protection for the eggs are necessary. Soft, slightly acidic water is best. In the morning sun up to 300 eggs are laid and fertilized.  The eggs sink to the bottom.  After spawning the parents should be removed. After 6 days the eggs hatch.  When the young fishes are swimming free you can raise them with infusoria and a few days later with Artemia-nauplii.
