After reading quite a few threads about what everyone is feeding there fish I decided to buy some better food. I have been feeding tetra variety mix with wheatgerm & garlic mixed in, about 2wks ago purchased some Japan mix from Queni Koi this has added prebiotics & probiotics I also bought some dried shrimp. When I fed the fish with tetra there was a delay before they ate it but now........soon as the Japan mix hits the water its like ive got a shoal of piranhas in the pond they do the same with the dried shrimp & meal worms I give them as treats I think the fish are happy with my choice of food.
