The 10mm pellets are the Mega, Mega is very hard to feed to rays or any fish, the 6mm pellets are allot easier and my africans/south americans/rays and everything else upto 12+ inches eats the 6mm pellets great. Like any food, massivore is like crack, it can take a little to get them off it but once they are its not an issue at all they will take it easy. And I feel the health benefits are way worth it.
I got the ingredient list off kens site for NLS mega....
Eitherway ill give the NLS a SHOT when I run out of my Massivore sack.
