Tricks to get fish to take prepared foods

[Canadian]

I picked up an ORA Splendid Dottyback last week and it was eating within minutes of being in the tank. It will take mysis without hesitation but I'm trying to wean it onto Spectrum sinking pellets (all my other fish eat this greedily).

Does anyone have any tried and true methods of getting fish to take pellet foods? I tried soaking the pellets with frozen mysis as they thaw but that doesn't appear to help much. Right now I'm at a bit of stand off and I'm simply only feeding pellets the last couple days hoping that eventually he/she gets hungry enough to start taking the pellets.
