I think I got it for like 13 bucks. Thinking back, I'm more convinced that the guy had no idea what it was so just threw something out there hoping I wouldn't pick up on it. Evidently it worked. So much for keeping the tank in the SA/CA vein. Ah well, he's a nice fish, but he's fairly aggressive. He tends to beat on my oscar a bit, especially at feeding time. Hence the fat piggish look. Although, most of hte pictures I've found of these guys look pretty fat as well. Maybe its just the body shape. In any case, I'm hoping that as the oscar grows up a bit, he'll be left alone more. The polleni doesnt bother the severums or anyone else in the tank, just goes after the oscar once in a while.
I could also see why the more recent pictures could look like a JD. The dark coloration and shiny blue spots do point in that direction. I've been trying to get some better pictures but I'm still working out the nuances of tank photography.
