I feed mine three times a day if I am home and twice if at work all day. They always seem hungry so i give them one pinch of flakes and if that is all gone really quickly add a pinch of tetraprima granuals. I get live food once a week and usually defrost a small amount of tubifex once or twice a week as well to replace the dried food. With 18 smallish fish from neon tetras to young gouramis i wonder if that is too much or not enough. They all seem fine but the betta gets very agressive over food at the top of the tank and the zodiac loach does as well amongst the bottom feeders.
