really, you jumped on amyjk for stating the obvious. that was when I got rude with you. I am trying to prevent you from making a big mistake. you don't agree with the fish/frog thing? this comes from your experience? no. it comes from your imagination. do you think I would say these things if I didn't see it happen myself. fish do not stay at the bottom. what do fish eat? flakes that hit the surface of the water! what does a toe do? the toe twitches and it looks like food. get your head out of the haze and do what it right for the pets in your care, not what your ego wants.
