Actually I just bought Kens Recently! What kind of large pellets you looking fore? He doesnt have carnivore specifically, but he has a bunch of nutritious mixes. And the pellets are quite large in fact.
Oh! well what kind of pellets? He has the sizes put on his website products. If you are talking about the Carnivore pellets from hikari that I am pretty sure they are 3 mm. so 3 mm and larger are good. If you are talking about the massivore... those resemble around 5-6 mm. But i'd just get his mix sinking wafers.. they are kinda like them anyways. what size are you looking for?
Not so sure about the massivore size btw. I dont use them. But that should be the correct size. anyone- please correct me if im wrong.
