Thanks for your advice, but my fish eating why i have to use medicine in my water the fish now eating well and i am mexin my seaweed Pellets with garlic maybe they will get fatty soonI'd personally would do the following which works wonders... If it's still eating then mix your food for 10 min in "API General cure" and "seachem focus" together in a 1:1 ration. I use the same spoon from the focus for both meds. Perform it daily for 7 days or when you see it start gaining.
PS make sure to keep the carbon running.
Good Luck
