I wouldn't bother making food for fighters. They only eat a little bit or should I say you should only feed them a tiny amount of food once or at most twice a day. You can feed them tiny pellets (2-3 pellet per feeding), flake (again just a tiny bit), frozen bloodworm (2-3 worms), white worms, mozzie larvae ect. The trick is to feed them till you see a slight buldge in the tummy.
