Why do you guys say skip live black worms? Do you think they aren't healthy or what's your reason for not feeding them?
They are fine for an occasional treat, or for a fish that won't eat anything else. But, IMO, when acclimating a new fish that is willing to eat marine based meats already, you are setting yourself up for a little extra trouble/work by offering live food that it may prefer, and become accustomed to.
I had to supplement my collare's diet with live blackworms for over a year before he ate frozen foods with enough regularity to keep him fat. It's not fun, so if you can avoid it, you should.
