I have a 5 inch long Ornate that I would normally would feed frozen bloodworms and beefheart to. Now he had this diet for approx a month before I decided to start him on a diet of Hikari massivore pellets which he really seems to enjoy as he eats the whole thing. However I have tried to feed bloodworms/beefheart multiple times now and he refuses to touch it, to the point that it just sits where it sank to. Is this behavior normal or not?
