I had a couple of inquiries about the caring of the worms, so I figured I'd post this link:

Here is what I have been doing daily (not saying my method is perfect, but has worked for me so far):
Storing
--- I use a large tupperware -- key thing is the largest length x width container you can find, the better. Ideally you don't want the worms to be "too much" on top of each other. I had a few casualties when I had 1lb of worms in my container because there was literally 1" thick layer of worms which, I don't think they appreciated as much.
--- Rinse/fill the container with chilled filtered water; just enough water so that it is 1/4"-1/2" max above the "worm line"
Preparations
--- RODI water in the fridge where the worms are, so the water is nice and cool.
Time of Feeding
--- Take out the worms and the RODI water, and walk to the sink
--- Pour some RODI water to stir up the "crap" ... so to speak
--- Pour out as much water as possible
--- Pour more chilled RODI water -- enough so that the water level is no more than 1/4" - 1/2" higher than where the worms are
--- Use a fork (or whatever utensil you prefer) to take out as many worms as you'd like to feed, put the rest of the worms and refilled RODI water container back in the fridge
--- <OPTIONAL> Feel free to cut the worms into smaller pieces if you're concerned about our fish not eating them. Initially my smaller anthias (ventralis) weren't touching them -- I started cutting them up, and they started eating them. Now they eat worms 2x their size

--- Feed the fish and enjoy the show!
Hope this helps!
