Nicely done. Ya mentioned before that the male beat the female pretty severely. I'd add some driftwood, pots or PVC caves, and some rocks to the tank, startin' at the left side of the tank and extendin' midway across. This will break up the line of site and give her more hidin' places and options for escape routes should he decide to put his wife-beater shirt back on.
Also, if ya extend some larger pieces of wood higher into the upper levels of the tank, it will encourage the fish to use a larger amount of the space available more frequently.
