Hello, my pet store by me has these are they good to put some in the tank for the fish im going to have ...
they are a high protein food and i suggest using them as a supplement and not a main food supply. don't know about angel fish but plecos also love algae wafers and veggies like zuccini.
i'd defrost them in a small amount of tank water before giving them to the fish.
Frozen are better than live. Less chance for diseases plus the frozen are usually gut loaded and filled with vitamins. Plus they're just easier to store.
Fish that don't need bloodworms (i.e. most fish) get them as a meal about once a week. I have some fish that won't eat prepared foods so they eat bloodworms more often (every couple of days or so).
