Even though Corydoras and Brochis are different genera, I think they all fall pretty well under the term cory cat (along with Aspidoras and whatever genus they eventually decide C. barbatus belongs to). As far as favorite cories, I like C. melini, arcuatus, sodalis and schwartzi. There are many more I've seen in books that are gorgeous, but most of them seem to be either unavailable or stupid expensive.
