Congo Tetra is considered by many to be the jewel of tetras in the home aquarium because of its natural beauty. They have flowing fins that some have described as shimmering and the main color tends to be silver with an orange glow.
Congo Tetra do well in a peaceful community aquarium that is well lit and moderately planted. They prefer to swim in schools of 5-8 in an aquarium that has plenty of room. It is best if this fish is the dominant species in the tank or it may become shy and reclusive.
The fish in nature approaches 4 ½ inches. However farm-raised varieties, though full finned and rich with color, will generally not grow beyond 3 or 3 ½ inches. They have long, flat bodies with large scales; males also have long, flowing fins that are violet with white edging.
What makes these fish special is their amazing rainbow luminescence in their bodies from back to front, They are generally blue on top, red and gold in the middle, and blue on the belly.
Congo Tetra are egg layers and because of this you must make sure if breeding to separate the adults from the eggs or the eggs may be eaten. Another consideration is that the eggs of this fish are extremely vulnerable to fungus and the aquarium should be treated accordingly.
The Congo Tetra will accept many small foods such as brine shrimp or daphnia, freeze-dried bloodworms and tubifex, micro pellet food, and a high quality flake food.
