Betta Fish: Thoughts after getting my first betta

I never had an interest in getting a betta but I came across a free 10 gallon tank and figured I’d look into getting one. They are awesome fish. My first day having him, he already knew I was his food source so he would greet me at the front of the tank as soon as I walk in the room. He’s in a 10 gallon and explores every square inch of the tank so I really think they benefit from a tank larger than 5 gallons. He has so much personality and is a really fun and inquisitive fish. I’m already considering upgrading his tank to keep him with some community fish like corydoras (I’m not sure if having a school of cories and a betta in a 10 gallon is a good idea).
