is my betta fish okay?

i’m a newly fish owner and i got a half moon betta male. hes been with me for over a month now but i always feel like im not taking good enough of him and im afraid of killing him. so betta owners, does he look ok? is anything wrong with him?? i’m probably freaking out over nothing but just would like some insight. he also keeps gasping for air and idk why. thank you
