I wouldnt recommed veggies for Central/South American Cichlids due to these cichlids are carnivores, and like meat. Unlike African Cichlids which are herbivores and prefer plants and veggies, CA/SA Cichlids need protien in their diet, if you havent noticed alot of the pellet bags have pictures of american or african cichlids on it, this tells you that the african pellets are high in plant/veggie matter, and american cichlid pellets have a higher dosage of added protien. This is due to their diet is totally different, giving African cichlids a high amount of protien can bloat their stomach and intestines which can kill them. Giving American Cichlids a high amount of veggie matter wont bloat them, it will only deny them the protien and other nutrients they depend on, thus making them appear skiny and malnurished.
