I'm a bit worried about the Cichlids you have with a Striped Raphael. I guess that you can try and see if the Cichlids ignore the catfish, then it should be ok. I have two Striped Raphaels and all my fishies ignore them.
Striped Raphaels easily go anywhere they want to and fishies generally do not pay attention to them. However, there may be conflicts if a Striped Raphael go into an area (hiding/cave location) thats marked by a Cichlid.
