Well I wouldnt really say harmony they picked out their new corners and are protecting it from mbuna african cichlids more than twice their size.They were originally in my 10 gallon just because I got them by accident.I wasnt expecting them to pair up so fast,like the next day and they were all and still are just juveniles a little over an inch.and it was 6 fish not 6 pairs.I dont really recommend anything else in the tank just leave them be and do what they know best breed!oh yeah as far as plants i have some live plants that helps out too...
