Attack dog....attack fish....same thing right? Thanks for all the advise. I am thinking I ring the bell and they bring the food to me. It might take some time but I think it might work.
I have one that I got when she was about the size of a quarter and thaght it was adorabble when I taught he to jump and take food from my hands until she started jumping clean out of the tank when I tried to feed her. She could even push up the lid and jump out so then we had to teach her she would not get a treat for jumping but it was still fun to have a trained fish
