My pbass been on the smaller size carnivore for 3 weeks now and the one that accepted the pellets for the past three weeks exploded in size. The other one just started eating it. I ordered the 13.4 oz of massivore since everybody swears by it. Checked the ingredient list on both and they are identical. So does anyone know if they are the same thing cause i saw on the hikari sub section of this forum and hikari says that carnivore has their special germ?
