Sometimes there are certain situations where a direct teaching approach is not possible. I found this out with newborns and fish. Firstly I am unsure if they are capable and secondly there is no direct feedback to tell you if they received the message. You then use the trial and error method: Try something and see if you receive a satisfactory result. Small goldfish are very skittish. This is reasonable because they are so small and have been largely mistreated. Here is how to teach them to eat vegetables.
