Quite difficult to identify from the similar looking C. agassizii especially as juveniles and knowing where your specimen(s) originated from is a great help. Also similar to C. leucomelas but this species is much smaller and has a very dark eye band. Body has dark brown spots and in the head region they form a reticulated pattern. The eye mask is pale and runs from the top of the eye and over the head. The black blotch in the dorsal fin extends into the body. Lineage: Placed in Lineage 8 sub clade 4 which comprises the "intermediate long-snouts" with deeper bodies. It also includes Brochis in sub-clade 1 which was synonymised with Corydoras by Britto in 2003 but in time there will be a revision which will resurrect Brochis (Cope, 1871) to full genera again. Aquarium Care: Keeping the Black-spot Catfish is no more difficult than any other of the Northern Amazonia species of Corydoras and it will make a nice addition to your community tank. Keep at least 6 of them, as with most Corydoras they like their own company, then you will find that they will not be so shy and you can see them during the day picking away at any tiny morsel that has been missed by the other occupants of your tank. If you keep Barbs such as the "tiger" keep a close eye on their dorsal fins as this is a waving flag to some of the more nippy species, then you will have to make up your mind to either move your Barbs, or your catfish, to another tank. Diet: A good quality flake food and tablet food for adults with sparodic feedings of frozen or live food will keep your Corydoras in good health.
