the mazuri croc chow have very high protein contents, I'd think too high as a staple. For common and Florida snappers I'd think a staple in fish wouldn't be the ideal diet either. I use aquamax 500 which are tiny pellets but I don't mind tossing a handful for my 22 pound 13'' common. They do come in different sizes some a large as marbles I believe. But the best part is that its cheap a 50 pound bag runs for less then 40 bucks.
