Lamarck's Angelfish not eating

Properly some of you seen my last thread about my angel suffering from really bad ICH. 2 or so weeks has pasted and no visible signs of ICH are present , so perfectly healthy.

However it hasn't eaten anything since i have had it , I've tried all these foods with garlic and without:

Flakes ( 2 types )
Algae strips
Mysis Shrimp
Brine Shrimp
Mussel
Prawn

It will not eat a thing ! It goes after mysis shrimp however spits it out. Its still very active and seems to be looking for food on the rocks and substrate.

All my other fish are happy and eating anything i put in the tank.

Ideas? :-/

Thanks
