Help Finding Tilefish and Powder Blue

[Zentof]

I have now been looking for over a year for a Purple or Flashing Tilefish (Hoplolatilus chlupatyi ) . I once owned one early in the hobby but it succumbed to ich before I knew to quaratine. It was my favorite fish ever and I can't find one ANYWHERE.
Does anyone know a possible source? I've been trying Quality Marine and J and L Aquatics (where I got my first one) with no success.
Also seeking a Powder Blue Tang to replace my ravenous Regal Angel. Thanks.
