Oh boy, if you are interested in getting into killis, you need to do a lot of reading. Different types will only eat different things, some will only eat live foods. I don't recommend buying eggs, it sounds tempting, but it's very hard if you don't know what you're doing. I suggest doing massive research into any type you'd like to buy, there are specialty sites dedicated to them. They are definitely beautiful fish, if not the most friendly. If you'd like some more info on specific questions, feel free to email me.
