Hi i have two oscars about 5 " , i feed them mainly on frozen prawn, bloodworm and frozen mussles. I also give a small feed of hikara chilid pellet. I am really wondering how much to feed these fish. i want them to grow as much as possible and they jus seem to forever want feeding, i am probably currently feeding each oscar per day , 2 prawns, 2 mussles and small feed of chilid pellets. is this about right? or too much or not enough. Many thanks!
