Betta Fish: Does he look healthy?

Hey everyone!

This is Dinky. He's had a bit of a rough go and been through a few different small, unfiltered, uncycled tanks with different owners over the past few months. Now he's in a 10 gallon with some cherry shrimp and snails, living the good life.

My question is: do his fins look ok? It looks like he has chunks missing in some spots. Overall, do you think he looks healthy? And would you recommend adding anything to the tank?

Any help or advice would be really appreciated! This is my first betta as an adult, and I wanna pamper him to atone for the sins of my childhood.
