Yea, planet Catfish has 20 species listed and two unnamed ones. I finally found identification of one, but the first one still stumps me.
This one was hard to photograph, but the color and pattern made me think of a Siamese Algae Eater. Tan on top with no spotting, thin dark midline all the way through the tail and tan fading to white under the belly.
This one was heavily spotted above the midline, and had a distinctive hexagon on the caudal peduncle.
Edit: Found the species. Otocinclus mariae. I rather liked it better than the more common vittatus.
Yup! I have four generations of sewellia lineolatus in the 125g. Also two more hillstream species and several goby species. The gastromyzon scitulus and g. zebrinus are proving more difficult to breed.
