Betta Fish: Went from a 2.5g to a 20g :)

I was gonna get my betta a 5g tank yesterday, but ended up getting a 10g out of luck. Today, I had to get something for the filter, my mom spotted a 20g tank for the same price as my 10g! So they let me switch tanks for free.

In the pic, there’s a size comparison between my 10g and 20g. Wild!
