I'm about to start treatment for these as well. I'm using Levamisole, the same type sold by INKMR to treat the water column. You really have to treat the whole tank, not just with food. The problem is once you see the worms from the fishes vent it's too late. They are dropping eggs already. So you have to treat the water column once to kill the worms in your fish, then once again about 3 weeks later to kill any eggs or newborns before they mature.
I am also feeding my fish the flakes from Angels Plus though in between treatments of the water column just to make sure I get everything completely.
I've done a lot of research lately on treating this so if you have questions let me know!
