I defrost mine and often mix up several blocks of different frozen food ... so the fishes get a choice. (Quintet, by the way just has five different foods in individual blisters - I often get that).
Then, like kribensis, I use a syringe to spread it about the tanks, so everyone gets a chance to get some .... and I squirt some extra hard, so that it reaches the bottom for the loaches and cories.
I only feed once a day and I use the frozen food once or twice a week. If I get live food from the lfs then I swop that for one of the frozen feeds.
