Ha ha!!! I feel that I'm the one in the fish tank when I am around my fish. They are extremely interactive and are very curious about the world outside of their tank. I can't get a decent picture of one of my fish, because he is always facing me, or turning. When we first got our fish, our cat, who had "only indoor pet" status became very jealous when we would watch the fish, she would cry piteously. We told her that she could be our pacu kitten. My husband would hold her up, rocking her while saying, "Pacu Kitten goes swim swim swim, pacu kitten goes swim swim swim" as he walked in front of the fish tank. There was literally a parade with the pacu swimming along side husband and cat--back and forth, back and forth the length of the tank.
Yes, they stare, but only because they are friendly, curious fish.
