Tetra Bits Complete For Tropical Fish

My hubby got new discus fish about ten days ago from his father. And along with them, my father-in-law also gave this food, Tetra Bits Complete, for the discus. It comes in a bottle and its written that its made in Germany, although the writings indicate Chinese and Korean language. It has 25% extra in it. My hubby gave this food once a day for his new discus at first. He said it would need to take time for the discus to adjust in the new environment. After several days my hubby began to feed them twice a day. The food really helps in enhancing their color, really. And although we cant see the growth yet because its still ten days of feeding, my hubby is optimistic that this food is great in helping their growth. Also, my hubby tried to feed his gold fish with this, and its good for them too. Compared with our regular food for the gold fish, he thought that this food is slightly better, for the gold fishs color is slightly brighter with this food. We think that this food is suitable for all tropical fish, and might want to continue using this food for the discus and sometimes for the gold fish.
