I may be the odd one out, but I've never thought that 'cory' means just bronze or peppered. There are so many cory species and pygmies are just one of them. It's the term 'pygmy catfish' that had me pausing for a moment as 'catfish' is a lot more than cories and I had to think what type of catfish it could be before I realised you were talking about a species of corydorasYes they are cory's but when most people think about cory's they think about bronze or peppered not there smaller cousin
