I have heard good things about that betta spa so it will be good to add. I will point out that to me his fins look fine. I do not see any rips or anything that looks "off" to me. His fins are ruffled but that is because he seems to have some rosetail gene which causes bigger finnage. Take a look at Sushi for example: the weird frilly look to the ends of the fins -- that is characteristic of rosetails and is not something that needs to heal.
