I have two red devils that are about 5" in size. One of them is
incredibly
aggressive and is literally terrorizing the other red devil, "he" just
wont
let the other one be. The more dominant one practically chases the other
red devil into corners, where he just attacks him mercilessly. I read
somewhere on the net that this is typical behavior of two male red devils
and that they will continue doing so until one they kill one.

Is there anything that I can do at this point to stop the aggressive one?
Should I introduce another Red Devil but a female or will it get worse?
If I take the aggressive one out will the other one become aggressive
toward
the other cichlids in the tank?

How big is their tank? Most large Central American cichlids are not going
to tolerate others of their own, or very similar, kind except in a HUGE
aquarium.
It isn't just a male/male problem with big cichlids (males and females often
injure the opposite sex also) they are just very
territorial fish. If they are both males, introducing a female may lead to
even more territorial behavioras the pair bond, meaning the rival male will
certainly be killed and the other tankmates will likely be also. Unless you
have a big, maybe 6' long or more, with plenty of hiding spots, I would
separate the two. They're not called red devils for nuthin' ;-)
