I cannot seem to get close enough to see what my Otocinclus looks like in detail, so I started hunting around the internet. I came across the site below that has a handful of thumbnails. These are all great shots, top, side, and underneath as well. Great pics. Enjoy. I did. The shot of the mouth is fascinating.
