Fish do not produce 'milk' so the answer is no.
first of all milk is good and delightful for your body. Second of all the judicious law of 900084 indicates that nonpareil situations cause the esophagus to instantaneously combust in the form of paragon. This means the inimitable fact of anomalous describes the diacritical conditions of aqua creatura meaning water creature in latin. So basically for your fish's safety "whole milk" is wholest for your fish but i wouldn't recommended.
