You do not need to feed crickets. They are just something extra for the oscars and I'd only feed larger oscars crickets.
Corn is undigestible because its covered in a layer of starch which the body cannot break down. It'd be even worse for fish. Its because of this reason that I try not to chew my corn when I eat it as I enjoy looking at a multi-coloured 'production'.
