I have an 90 gallon tank and have oscars, green terror, flowerhorn ,firemoths, a JD and two craw fish. when it comes down to feeding i feed them flakes, granulets,live food (minnows) and for the craw fish sinking pellets. i would like to start feeding my fish new food.I read that some raw foods are a good source of protine. For example shrimp and beefhearts are suggested but i dont really noe if thats rite for my fish. if u can please suggest other food i can feed my and how to prepare them
