Those aren't real copepods Gresham, You can't many culture any fish on harpacs. They are not worth much in regards to larval feeds, some will even eat your larvae.
Calanoids are very different, require much stricter culture protocols and food. You'd need a 20L or so of top quaility algae a day to maintain a good calanoid culture; and that is at small scales.
