Here are some pictures of my new payara which I'm 99% sure is a Hydrolycus scomberoides. I was surprised to find one in an LFS, but they apparently have had it for over a year or two and I hadn't noticed it! It's about 7" long and is very tenacious; it latched onto the net at the LFS when it was being removed from its aquarium and did the same when I was transferring it to my aquarium.
I apologize for the algae on the glass; I need to get a new scraper.
