Hello, I just recently set up a 75-gallon tank with very good filtration and all of the works and have just got 2 small Oscar fish. The problem that I'm having is that I don't know how much to feed them without overfeeding them. So far I have just been overfeeding them because I can see all the uneaten food on the bottom of my tank and an almost cobwebby like substance over the uneaten food. I have 1 albino oscar which is 3 inches long and another Oscar which is around 2.5. I have been feeding them Spectrum cichlid pellets that are about 1mm in size. I am lucky that I have 2 powerful filters but I'm scared that I'll kill my fish if I don't get this under control. In addition, I've only been able to feed them twice a day because I am not home for most of the day and when I feed them the first time at 5:00 am they don't eat it. I'm going to get an auto feeder soon but I don't know what to do.
