I used to have a goldfish pond in the back yard, and some of them would eat from my hand. But my DP Homer seems to be the most interested in me, whether I have food or not. When I vac the tank I have to move him out of the way so he won't get sucked up... not quite so bright, but oh so cute! My pair of blue rams are quite interested in what's going on too. They'll follow me around the room and, again, I have to scoot them away when I vac their tank, too.
