Hi Doug
 
Congrats regarding your recent adoption of Tuck - I wish you many happy
years together!  : )
 
Regarding diet, many reputable sources recommend a kibbled food that
contains a minimum of 32% protein and a minimum of 18% fat.  Poultry and
other meats should make up the first few ingredients listed on the bag,
while corn and other grains should only appear further down in the list.
Popular brands include Totally Ferret, Eight in One Ultimate (not Ultra
Blend), the Ferret Store's Superior Choice, and Eukanuba Kitten.  You can
purchase these and other diets at the Ferret Store:

The Marshalls diet that you're feeding right now isn't the worst, but it
isn't the best either.  If nothing else, the fish meal in it stinks and
it will make his stools smelly!
 
As for switching Tuck over to one of these healthy diets, you may wish to
