Ok after due thought it was time for drastic measures, the garlic worked but in a different way. i put about 50 flakes of chopped garlic directly in the tank and left it overnight. next da morning i saw the poor guy skimming the surface for food. he was not able to eat any of the big pellets. he startes eating fine tubifex worms. i have to crush the cubes into coarse powder and he eats these. not eating much but this seems to be an improovement. i will be doing a WC on sunday so i think i will add some more garlic now and remove it tomorrow morning, followed by regular feedings.
hope he attains a good appetite...... thanks for all your help i will keep you guys and gals updated with the results
