Oscar feeding

Question
My two oscar fish, size 4-5 inch, used to eat normal floating foods, but since a few days back, they want to eat only non-veg (blood worms etc), I want to avoid it.
I am having 2 Piranha (10inch), parrots, tinfoils,  they all eat normal foods.
Please help me to avoid non-veg.
Regards

Answer
well try feeding the oscar "beefheart" or "Omega one super color pellets" get the large size pellet if you can and they should eat those. This is what i do i put the foods in front of the filter waterfall so they go down in to the water instead of just float
