Well apart from the fact thats it cruel to the goldfish most feeder fish are grown without consideration to disease transmission and kept in really bad conditions .... I dont eat veal and would you knowingly eat beef infected with BSE ? just as an example of what its like

For one once they eat live food, its incredibly hard to switch them to prepared food. They spoil easily basically. Another factor is feeder goldfish tend to be prone to carrying disease, they are not kept in the best of conditions and generally have stressful lives. After having worked in a pet store when I was in college I can safely say they have massive die off and that employees dutifully remove the dead every morning usually before customers come in the store. Get them on prepared food and keep them there. That way you know exactly what they are eating.

What kinds of prepared foods do you suggest?

Oscar would enjoy a good quality pellet food such as Hikari Bio- Gold along with freezedried shrimp or shrimp pellets,frozen Krill ,frozen shrimp, freezedried crickets such as those offered to reptiles(lizards) and chopped earthworms.
I would submit that minimum tank size for one oscar to be 75 gallons with filtration cpable of filtering eight times the volume of water that the tank holds each hour.Example..75x8 = 600 gallons per hour.
Water change of 50 percent each week.
Feeding Oscars as mentioned ,,live foods such as store bought feeder fish, is quickest way to introduce disease and the Oscar would /will..do much better with prepared foods mentioned.
Not providing proper enviornment (ie) large tank, proper diet,Lot's of filtration, and large weekly water changes, is primary reason that Oscars don't reach size potential before they succumb to sickness and disease.
Adult Oscar can reach 12 to 14 inches with proper care and they are NOT an easy fish to care for properly and many ,many, folks do not provide these fish with much of a chance of ever reaching their potential.
Most of the Oscars purchased or offered for sale are juvenile fish that may do ok in smaller tanks for three or four months but when they begin to out grow the tank, despite promises to provide larger tank as the fish grows,they often become sick due to water quality issues,improper diet,inadequate filtration,poor tank maint, or all of the above.
Oscars can live ten to twelve years and this should be considered before purchasing these fish. If one is not prepared to provide for the fish for it's lifetime, then one should not purchase the fish.
If everyone who declared..."Oh I plan on getting my Oscar a larger tank in a few months" did so,, you would see many more adult oscars in aquariums ,and far fewer in lakes where they pose a threat to native fishes through predation,reproduction,and by competeing for same foods.

The most important medication in your fish medicine cabinet is.. Clean water.

A couple of reasons. For one, the goldfish you buy from the store are kept in horrible conditions so the feeders often come diseased, which passes on to your oscar if he eats them or even if they're in the same tank for any amount of time. Also, goldfish have serrated spines that are known to injure the fish that eat them. Finally, and I always forget the details of this, but there is a certain chemical found in goldfish and other coldwater fish (like rosy reds, which are another common feeder fish) that causes a vitamin deficiency (thiamin, I believe) in the fish that eat them regularly, which leads to other health problems. Oscars don't need to eat feeder fish but if you want to make live feeders a part of their diet, I recommend setting up another tank and using that to breed your own feeders (livebearers work really well).

Thanks for the replys. I didnt used to like them much but recently Ive found them to be pretty awesome. Ive been looking around for a large tank for a good deal. If I find something large enough then I may have to buy it and get it cycled, we'll see
