The Congo Tetra (Phenacogrammus interruptus) is a very pretty fish that comes from the tributaries of the Congo River in Zaire.
Preferring slightly acidic waters and murky waters they get to around 8 cm if given the time and the space to grow. They are very easy to keep and the males does grow these extraordinary long streamers that makes them absolutely divine in the tank.
They prefer a temperature of around 26 to 30C and they prefer a pH of around 6.5 to 7.0.
We have had Congo Tetras in our store for quite a long time and they have enjoyed being such a delightful staple within Nano Tanks Australia and OzDiscus. In fact they are so pretty that we put them in our display tanks.
When you are looking for something that will go with Discus or Angelfish give Congo Tetras a go. They keep to themselves, they are easy to feed and easy to keep.
