I have a 55g with 10 F1 Tropheus duboisi and 3 F1 Tropheus black "bemba" and was wondering what the best food to feed so I can get them properly conditioned for breeding. I feed them NLS thera+, hikari cichlid excel, romaine lettuce, green algae sheets, and twice a week a few whiteworms. Any thing else or is this an ok diet???
