Phenacogrammus interruptus

Phenacogrammus interruptus (the Congo or Zaire tetra) does not share the same origins as other Characins. It lives in shoals in soft, mildly acidic conditions, and needs plenty of swimming space. The male is recognizable by the tubercle on the middle of the anal fin. Size: 10-13 cm.
