A Fish That Likes To Be Petted!!!! :D

My dad told me something that he figured out the other day. Every time we enter the room and look at our red devil(a kind of fish) Henry, he swims to the surface...Before, we thought that it was because he was hungry, but now we've realised it was because he wants you to stick your hand in the water and pet him!! I actually tried it, and you could feel his smooth fish scale bumps as you petted him!! It was really cute and cool! When I figure out how to put videos on here, I'll make a video of Henry being petted. It's actually very cute!!  >.<
