Betta fish afraid of cory catfish

Byron said:

It is not advisable to have other fish in with a male betta. The betta may take a dislike to the other fish in his space, or the other fish may decide its fun to pick on the betta. This is not uncommon with sedate long-fin fish. Cories are perhaps usually OK, though I would not do this myself. The cories cannot damage the betta like upper fish could. From your description here, the movement of the other fish may annoy the betta. If the beta was living alone peacefully for a time, the sudden appearance of other fish bumbling around his space may un-nerve him. It bears close monitoring as it could suddenly get much more serious. We can't tell, it depends upon the fish.

By the way, which species is "Emerald Cory?" I've seen this name used for Corydoras aeneus, and also for Corydoras (Brochis) splendens. The latter grows larger and needs more space.
