Advertisement So I most typically feed my roaches oranges, though sometimes greens and other vegetables safe for my skink. But I always gave a variety of oranges, today I gave them blood oranges.(Usually navel.) Whenever I read "Give them oranges." it never explained WHICH, so I didn't think it mattered. But onto their reaction, while half of them are greedily chewing on the orange's flesh, the other half seemed to be utterly disgusted by the fruit. (They're on the opposing side of the container, completely avoiding the item.) Is this something to worry about? Did I just poison my roaches? They are Lateralis.
