Or at least, that's how I defined the look he gave me! I gave Hector a freeze-dried bloodworm today for the first time (just bought some!), and he scarfed that puppy down like none other! Then he spent the next five minutes prowling the top of the water in search of more, occasionally swimming over and giving me a look. He even flared at me! It was pretty funny.

HAHA I love the reactions fish have to new things! I like to give my new bettas dried blood worms right when I bring them home since they probably have never had fun treats like that before. They always FREAK OUT!
