Thank you all very much for your input, it is much appreciated. He is no longer eating the 6mm NLS pellets he decided he no longer wants sinking food. He is now eating on an alternating schedule of Hikari, Chingmix, Hikari, Chingmix and seems to be doing ok. After the storm when we lost power two days for about 12 hours each day he was very faded from his tank temperature dropping. He is doing quite well his colors are back and a deeper red then ever. I am worried lately his poop has been gray (it's definitely not white) I am afraid it is hexamita so I have dosed his tank with epsom salt @ 1 tablespoon per 10 gallons. His food is also being soaked in it prior to feeding. He chose not to eat it yesterday but today has since changed his mind. His appetite and energy are still good so I am hoping to catch it early. I am feeding him twice a day about 6-8 pellets per time. Any other advice/tips are appreciated.
To add some more advice, stop feeding chingmix. It has too much protein and not good for his digestive system. Hikari is ok.
You can get him to eat NLS again by starving him, but it sounds like your FH might have hex. Could also just be stress. Your doing the right thing by soaking his pellets w/ RD's method. Just do water changes everyday and worst case scenario add some Metro in the tank if he's not showing any progress.
Also, like RD stated, the 6mm NLS was too big, just break them in half and he might eat them. The garlic could have helped prevent parasites. Good luck.
