Dear Neely,

As a science cat, I handle going to the veterinarian better than most. I see it as a meeting of scientific minds. But I had no idea some veterinarians specialize in fish.

I learned all about fish medicine from my friend Nora Hickey. She’s a fish veterinarian at Washington State University. She works in the Washington Animal Disease Diagnostic Laboratory. She helps fish at zoos and hatcheries stay healthy.

Hickey told me you can watch a betta's behavior to see if it's happy. Happy bettas swim around. They interact with things in their tanks and act interested when you come close.
