I have a group of 8 Black Nangu Compressiceps. They have just recently started spawning so are still nice and young and will be producing fry for a long time to come. I have a hard time sexing them but I believe there are approx 3 males and 5 females, but that is my best guess. The largest is around 3", with the guessed females still being smaller. $320 OBO for the group. I have a 9th I will throw in for free if it is wanted, but it has something strange with its mouth. It was not like this when it was purchased so it is not genetic and does not seem to bother its ability to eat. Its almost like its. . . stuck? in a downward position *see picture*. Will ship, but only overnight.
