This is a photo of my larger featherfin catfish. It's a nice looking specimen, but a bit of a bully, particularly intolerant of my Corydoras sterbai and the smaller featherfin. My Ancistrus sp(3) also gets into skirmishes over good hiding spots, but surprisingly the Synodontis cats usually have to yield. I'll probably try to give both of them to someone with a more suitable tank and perhaps get some S. nigriventis instead.

Synodontis eupterus - ca 10 cm (4 inches)
