I don't have any experience with angelfish, but I started with two blue gourami, one started bullying the other so I got rid of one.. Anyway, the one gourami started to be a bit of a bully towards my corys.
I'm sure many people have done it with success, but it didn't work for me. If you do get some, make sure you get a group of the same type.. They're much happier that way (this is another thing I messed up with!)
