Thanks to all for your excellence responses. I have never seen Hikari pellets, but they sound like they are worth looking for.
As to bloodworms, Mr Foosh (aka His Royal Highness) has absolutely no problem with them. Heck, I could drop the whole container in and he would pig enough down to look like a blue tennis ball!
I am going to try and stay the course with the Top Fin pellets, but will certainly be ready to change if he continues to ignore them.
Thanks again to all. I searched for and found this site in desperation, and you have welcomed me like family. Thank you.
