The Congo tetra has a typical full-bodied tetra shape with rather large scales. When mature, the iridescent colors of the Congo tetra run through the fish from front to back, starting with blue on top changing to red through the middle, to yellow-gold, and back to blue just above the belly. It is not its fluorescent colors that make this tetra so distinct, but rather its tail fin, which develops into a most beautiful grayish-violet feathery appendage with white edges. 

Species – Congo Tetra – Phenacogrammus Interruptus

Current Size – 2cm – 3cm

Adult Length – 6-8cm

Temperature Range – 23 – 28 °C

Tanks Mates and Compatibility -  Peaceful but may scare shy species with its active swimming and large adult size. Recommended for most community tanks however. Ideal tankmates include other tetras, rainbowfish, Corydoras, Loricariids, Synodontis and various peaceful cichlids such as Pelvicachromis sp. or Cleithracara. Do not keep congo tetras with fin-nipping species as the spectacular fins of the males will be destroyed. Similarly, they should not be kept with boisterous tankmates due to their shy nature.

Ideal Number to Keep - The Congo Tetra has a very timid temperament and should be kept in a school with at least 6 individuals. They get easily frightened and need a school of their own kind to be comfortable and thrive.

Feeding -  Relatively unfussy and will accept most foods but live and frozen food should compose a good proportion of the diet in order for the fish to show their best colouration.

We recommend:

Please note – Some images used are library photos and will show the colour potential at a fully mature size, as our fish are juveniles they may vary.

We always aim to supply the fish as close to the purchase size as possible. On rare occasions if this is not possible we will contact you.

The fish are selected at random however you are welcome to make a note on the order and the fish manager will do his best for you, requests are dependent on stock at the time of your order.

    I purchased 10 Congo Tetras. I received 5 males and 5 females. They arrived in excellent condition and, after spending a week in quarantine, I added them to my main tank. Great quality fish and great service. 👍🏻
