Sure hope things work out for you. Mr. Foosh absolutely turned his nose up at Top Fin pellets, so I fed him bloodworms for a week because I was in the middle of a crisis at work and did not need more stress. On the recommendation of several people here, I picked up Hikari Bio Gold pellets, but I also picked up Hikari Brine Shrimp cubes. I gave him Brine Shrimp for two days, then tried him on Hikari Bio Gold. After one day of Man vs. Foosh (he is a bit stubborn), he decided to try the Bio Gold and now he loves them!
So maybe try him on something other than bloodworms or pellets first, then try pellets again. It might work...
