Hi! I am having trouble developing a balanced diet for my Russian tortoise Otis. I have been giving him a variety of greens since I got him in June, but now it seems that he only wants to eat lettuce and broccoli. I know that both of these are not ideal. I just looked up broccoli on the database, and it is on the "Do not feed" list! Otis LOVES broccoli. I have ground up Repashy superfood and put it on the lettuce - he won't eat it. He does not eat cuddlefish bone either. Any recommendations would be greatly appreciated. Thanks!
