I feed my 08 royal (400g approx) every 7-10 days on rat fluffs, but lately hes been hungry just 2 days after? He cruises around his tank, like he used to when he got hungry but not a week later, just a couple of days! Do you think he needs bigger rats? What is the size difference like between fluff and the next size up? When ever you go near the viv, its like hes ready to strike for his food, like he hasnt been fed in months!! It might be that hes a gannet and would eat every 3 days if he could!!
