i feel that your best bet is to feed him up on live river shrimp and earthworms and then let him starve until he starts eating ! mine took 7 months to get feeding but he will now take anything ! i didn't starve him for all that time though just fed him some of the above occasionly to stop him from losing too much weight,above all be patient but do feed him up first before trying the starving technique lol good luck Paul
