They are real characters for sure. I can tell you, for example, that ours seems to recognize both me and my wife as opposed to other people who might be in the house. Also, he clearly watches me when I go into the kitchen and if he sees me pull a drinking glass from the cupboard (which is what I use to thaw out and then bring him crayfish with) even just to get myself a glass of water, he becomes very excited.
He cannot do this now, due to the position of the TV in relationship to his tank but before, when he could see the TV, he did appear to respond to certain images that would come across the screen. Also, we have a shrub putside the front window that produces a large flower which is bright orange and somewhat crustacean-looking. If the breeze is just right, those flowers sort of dance around outside the window and he gets really excited when he sees that. A very interesting fish, probably lots going on up in his head. I need to set up some tests and video them.
