I'd say yes, If it's accustom to live prey then you may need to use chopped frozen meaty foods as a stepping stone, but once they get the hang of grabbing food as it sinks to the bottom/hits the surface instead of hunting it then they will quickly stop looking before they grab at food and will eat just about anything you chose.
I also find fish , and most animals, eat better on a schedule . If you always feed at the same time of day and establish a routine then it's easier to switch them from one food to another. They quickly learn when it's "feeding time" making anything that hits the water food.
ok, but in the mean time while i starve it do I need to worry about my micro cheating on his diet and eating the oscar of pleco. Both are about 5-6" smaller than my micro
