It'd be my guess they were starting to have problems with the N. buescheri.
X. melanogenys is found in the lake in large groups and the males
continuously display to each other. Territorial battles usually end there.
As for eye biting in the Malawi species (Dimidichromis) this is more of a
nick-name than an actual trait chartacteristic of the species.
There are several people on our site that keep X. melanogenys as well as the
other Tangs you've mentioned, they may have more info for you on keeping
them in a tank.
