populating my wife's 100 Gal fish only tank with copepods


Hey everyone I have ordered a 16oz bag of live copepods for my wife's 100 gallon fish only tank and as of now it has 4 emerald crabs, snails, and a Green Chromis plus I have 9 more Chromis in Quaritine but my question is because I want the tank to populate with copepods as a food source alone with me also feeding how long sould it that for it to be able to populate to a point it will continue to be a secondary food source in my tank when we add other fish ?
