With discus, sometimes it takes time. It's not uncommon for discus to not eat for over two weeks in anew environment. May be they are not happy with the new environment. Not sure what you can do to make them feel more comfortable, but once they are settle in and feel comfortable they should start eating. What temp are the discus in? May be you can raise the temp and see if that helps. May be you can reach out to Hans and see if he has any suggestions. Hope they start eating soon. Having been disus keeper for several years, I know how it feels when your discus are not eating. Good luck!
