Are you confident of doin a Epson Salt bath for your fish? As far as i know, if he isnt accepting food, he is less likely to accept medicated food as well which leads me to believe your last resort is to give him an Epson Salt Bath.
What i do is this:
Remove enough water from the tank and put it into a bucket so that the fish can swim comfortably. I am careful to measure the quantity i am removing cos this is important for the next step.
For every gallon of water, i add 1 tbl spoon of Epson Salt (Magnesium Sulphate). 1 Gallon of water: 3.84 liters. To keep it simple, use 1 tbl spoon of Epson salt for every 4 liters of water.
Put the fish into this solution for a period of 30 mins or till he shows signs of being stressed.
Top up the tank with fresh water and drop the fish back in.
Repeat daily till you see his poop coming back to normal.
Just cos it happened to you is no means for you to claim that it will happen to me. Exceptions aren't the rule.
thank u sir i will do that....one thing i want to share some person told me to add 2 tablets of metrogyl 400 too into the epson solution???? is it right
I wouldn't go for Epsom salt yet. Treat him with metro IV not tabs since he is not eating. Also bump the temp to 32-34 deg. As per the pic it seems he is fading. Treat with metro + salt higher concentration. That's all.
I have never kept a flowerhorn. am one of the last few purist hobbyists. what i suggested, is what i follow. I dont like treating with meds. i try, as far as possible to keep the chems away from my fish.
That tab method that has been suggested, i wouldnt know about. Maybe someone else can vouch for the effectiveness.

metrogyl method is one of the most effective and acepted method worldwide for treatment of helminthis/intestinal worms.though garlic too is very effective in this case. i too like Zakk am very reluctant in using chemicals in my tank and would stick with more natural method but if the infection is very serious and prolonged i would suggest going the universal way.
viresh, epsom salt is good if ur fish is having bloat
but metro treatment is done for internal parasites, more like cleaning the interior system
but to tell the truth, there is nothing better than keeping a fish stress free, and u will never need meds, as the fish's immune system will take care of everything
