Just got back from the OCA Extravaganza in Ohio. Found a cory that I had not seen before. I was known as CW-32 but more recently was given the name Corydoras knaacki.
You can find a picture of it at this link. http://www.scotcat.c.../c_knaacki1.htm Mine are quite small so it will probably be spring before they are big and old enough to spawn.
