Before I got my bettas, I had wanted fish for a longgg time, but I was too busy with school and being sick. Whenever I went to the petstore I would be drawn to the fish section, and would spend forever looking at all the fish.
I finally got my bettas, and love them so much! They have greatly reduced stress (although one causes me a lot of stress - Drama Queen LOL). I really enjoy watching them swim, flare, build bubble nests. I even find cleaning their tanks very relaxing. My mom thinks I'm crazy XD
I think any kind of pet can be very relaxing and therapeutic.
