Think they might be unhappy with the lack of attention during your JPN Trip rather than feeding regime.
(They were suffering while you were enjoying yourself with the Shark!)
However for your reference, I feed my tank with
DT's Phytoplankton, 5 in 1 coral food, mysis, Henry's food, Artic pods, Rotifiers, NLS pellets.
but I only target feed my suns. will try target feeding my yumas and blastos once a week soon.
I dose with Strontium, dKH buffer, MG, Iodine, Trace Elements, calcium weekly now.
I have stopped using distilled water from NTUC.
Currently just adding water conditioners into tap water.
