Sounds like pairing behavior. Anyone dealing with cichlids should always have a divider handy, pairing behavior can get a bit nasty at times, requiring a time out. Some caves and other decorations for hiding will help, as well as provide a spawning area should this occur.
The tetras are an excellent idea, not only as dithers but as a natural barometer of the safety of their environment. Neons or cardinals work well for dwarf cichlid species.
