The other day he learned what the food container is. Now he can distinguish my fingers from the food container. He doesn't get too excited at my being in front of the tank until I'm holding the blue food container. He was following my fingers around the tank today, I'd have tried to get him to jump but I'm still afraid of his sharp mouth getting my fingers. I put a fake fish decoration next to the tank and he hid from it, then would inch closer, then when he got within a few inches he'd go back and hide and stare at it. He's certainly got a lot of personality.
