I discovered something today. I can call Hewbie’s name and he comes right up to me he will be on the opposite end of the bin and unable to see me and when I call him he comes excitedly swimming over and pokes his little head out of the water. This is something I never truly thought about but realized today. Fish do in fact have ear canals and can hear and there have been multiple studies of them responding to music and how they can hear different frequencies. And it just occured to me Hewbie is probably aware of what his name is and literally comes when called responding to my voice. I have tested this theory out a few times and every time I’m in the room where he can’t see me I call him and he swims really fast towards me. Fish and especially Hewbie are a lot smarter than we give them credit for.
