I have a pair of 5"-6" Polypterus Palmas Buettikoferi. I'm looking to trade one of them for another type of bichir. I am only looking for a Retropinnis, Palmas Palmas, Mokelemebembe, or Weeksii. I would do a even trade for a Retropinnis or Palmas Palmas, Mokelemebembe and Weeksii I realize are more expensive so maybe could work out a deal on the Palmas Buett and something else. I also have a 9" Rhino Pleco I could add as well.
