Years ago I raised a couple of pet oscars from barely fingerling size to better than panfish size. This was long before oscars took over the entire drainage system of Southern Florida. I learned very little from them except that they were willing to eat rain or shine, high barometric pressure or low barometic pressure, and night or day. They never turned down a gyppy or brine shrimp that I can remember. I fear for our native species in Southern Florida if these fish were typical oscars. 8T
