Yes I read Ben's new post. I was told mine were Comb spined catfish from Papua from my supplier.. he has been on point so far with ID. I've compared what is available on the internet that I could find and still can't say for sure which is which...but I'm no expert.This ID thread on allegedly the same Papua catfish as yours are would be of interest to you. If your and Ben Amiidae's cats are the same, Dr. Heok Hee Ng says they are not what you thought / stated. Not even the same genus: http://www.planetcatfish.com/forum/viewtopic.php?f=13&t=46258#p311789
They are Sciades (or Neoarius, depending on who you choose to follow) leptaspis.
