are 3 Tank transffers of 3 days enought for established fish??

[sensei]

I have a unicorn tang that is 9 inches big. He has been 4 years in my 150g dt. He is to big now and since I did not treat fish in my fist aquarium I am doing TTM before he goes in my new 470g dt when I have treated and observed all fish before putting them inside.

the thing is that he ate the fist 3 days of TTM but he has stopped eating, and I read that; " The trophont feeds on the body fluids and cells of the fish for
about 3"“7 days before leaving the host.". if this is the case 3 Tank transffers of 3 days are 9 days so it should be enought for heim, since my old 150g neven shown a sign of sick fish.

Can I know how many days can a fish live without eating?

Thanks a lot for your help

I think he is not eating because of stress.
What can I do to relieve stress levels??
Would moving him to my 470 relive stress even if I hace more fish in that tank even if he would be the bigger fish 9"??

This is the reason I don't do ttm. 2 weeks of hypo would do the trick. Good luck with your unicorn. Did ttm in the past and lost lots of fish.
