Okay, I've grown my group of Armatus out and it's time to hit the "Big Tank". I currently have some well fed Armatus, a few of which are 7"-8" and a couple that are 10"-12" that will be in a 270g. tank. The perspective tank mates are Endlis and Delhezis that are 7"-11", a few endlis are in the 6" range and are a concern. These Armatus have never had tank mates other than eachother and goldfish/feeders and I wonder if they'll murder some of the Bichirs. I know Armatus tend to go after the "shiny" fish but still a little concerned. I'm considering taking out the smaller Bichirs as precaution. Any input from the gallery?
