Mine watches me, they seem to be interested in you faster when you put them in the 5 gallon for the first time. At least mine did it with the 2 gallon. I think he watches me a little bit when I sleep too, noticed him staring at me one night, it was kinda creepy lol. Now he greets me in the morning and stares at me when I sit at my computer, so I agree I'm sure your guy will come around.

R.I.P to all my other fishes who didn't survive long enough to have a name.
