Seems he like zucchini . Also right in front of his dorsal fin there seems to be a lighter white spot, do you see it? Its like right on one of his spots, easier to see in the second pic.
Ok, the eyes are relatively small, so I don't think it's a L102.
Now it's between L201 or 142 (or something else that I haven't offered as a guess). If I had to guess, I would go L201. Hopefully someone else can let you know better if it's one or the other. (I think counting fin rays in the dorsal can help with the baryancistrus-142 vs. hypancistrus-201 question)
Looking at the pics of L142, L142 is like midnight black and their spots are bright white, but this guys, depending on the light you lookat him under, his spots have more orange in his spots and he isn't as black. I got him for 45 bucks, think it was a good deal? Also any idea on the age?
