Well, simply, don't give it to them.
This sounds harsh, but don't let the fish train you. Very few predatory fish are so stubborn that they will starve to death instead of eating something else. YOu may not have to feed him for awhile until he gets hungry enough to try something else. This is common with lionfish. It is unfortunate, IMO, that you have an LFS that feeds life feeders for these fish. It really isn't typically necessary.
But basically you may just have to overcome the feeling that you are not taking care of the fish by letting him go without for awhile.
But first just try and see if it will eat anything else. May surprise you
