I’m going to say Betta fish, mine is trained to jump out of the water and touch my finger! Sooo sweet (which is really funny because people don’t think of fish a trainable)
My Betta fish comes to say hi whenever my bedroom light is on. He likes to hang out by the food hatch too, always hungry lol. I’ve trained him to jump out of the water to touch my finger and goes through hoops. He also has a little LEGO boat he likes to play with. Such a personality!
