I recently picked this up from a LFS where I picked it out of a 100 gallon tank full of A. gibbiceps, A. agassizii, A cf pertensis and discus. It was the only one.
It is currently in quarintine because most of the fish in the tank were infected with ich. I have kept this species twice before and this has always been one of my favorite apistos. This species even adorned the header for this blog a few months ago.
