Protein describes an ingredient in the fish food. it will have a number beside it advising you of the pecentage of the food the protein fills. There is no specific limitation of protein in fish pellets, simply after research the best balance of ingredients has been decided and that is what your pellets should contain. Most successfull aquarists give their fish special treats of live food a few times weekly just to make sure their fish get a properly balanced diet.
