Two of mine like to watch netflix with me. One loved Thor, but he's fairly young... I think it was all the flashy stuff.
Little Boy and Fluffy both watch my community tank (tetra tetra tetra guppy molly) that also has two girls in it.
Glee is beside my 6 girl sorority, they're in a Hex-5 right now, next weekend he gets to be in the Hex-5 while they're in the 20 long.
I've got a veil tail beside me that watches me playing Everquest 2.
The mirror is a useful idea, walmart has little folding stand mirrors for a couple bucks, I use one because I can lean the mirror against the tank.
Little Boy will flare at it until he falls asleep!
