Does anyone know why a lot of people say that feeding your fish any vegetable matter is bad for your fish? I try to read a lot before I buy a fish on how to take care and what to feed. some books say to give lettuce, broccoli, and other vegetables. I have a fox face, and some tangs, that love the romaine lettuce. I also provide a lot of dried seaweed and mys sis shrimp. any input on this would be greatly appreciated...:eat:
