Darwin, my fantail goldfish is taking to training like a duck, errr fish in water. Today he performed his first trick, swimming through a hoop (which you can see in the video below). In fact, he loved it so much, when it was Sisco’s turn, he kept sneaking underneath the curtain to get more chances! We couldn’t stop laughing because he wouldn’t stop. Sisco on the other hand, is not taking to training as well. I’m using softened and cut pellets. He definitely seems to be more of a flake food type of guy. I’m finding that yes, even fish have reinforcer preferences! I’ll try to post more videos as training continues. Enjoy!
