Much better pics! I going off of planetcatfish, I'm still feeling pretty good about my previous selection but I'm not as familiar with hypostomus as I am with other genus of plecos.
You may want to check with Jason or Wes, who both see a lot more fish up close and personal than most of us. Perhaps they can shed some light.
Bummer you're in Canada, I'd have made you a generous offer on it
