My partner read something about fish liking you talking to them, so he started to talk to my betta Cerulean. I started too with "hI Cerulean. You a pretty boy? Yes you are." When he was new, he was doing everything opposite to what I've read on how fish act, so I'd go with "you a little weirdo? Yeah you are. Who's a weirdo." Lately he's in the front whenever I come to the glass; I'll tell him he's a model.
