you should be able to find chinese broccoli (green leafy veg, nothing like normal broccoli), bok choy and rocket at coles, woolies normally have baby endive, and fruit shops generally carry everything good. The only dark leafy veg that is considered bad is spinach because the oxalates in it hinder calcium absorption. Other good additives are green beans, butternut punpkin, carrot occasionally,...i'll pm you a food list, its american so theres a few things that are harder to get here or go by different names.
good move seperating them, i cant house mine together, even letting the girls have sun time together turns out badly,...
