I've had one of those in my hap community as well,boy this brings back memories.There was a great shop here years ago that seemed to be able to bring in every known African cichlid that there is but they have closed down unfortunately.Kind of partial to D. Strigatus myself; however, in my brief experience with them...they always seem to turn dark and start chasing around much bigger tank mates trying to be boss...which works for a while until they are put in check. They are beautiful fish.
