I agree with the above advice and I have been meaning to ask around and see what other members feed their dorado.Mine gobbles up the feeders that are intended for my bass,I dont want the dorado to be hooked on feeders so I try to give him a variety of foods like krill,flakes,and the occasional cricket.I have two but had to separate them or I would end up with just one.The other dorado is in my wifes aquarium in her classroom untill school is out.They are a very quarrelsome fish unless kept in groups.
