welcome to the forums of this great website! c:
i'm not exactly sure what to do about the flaring, but the bubbles are a bubble nest!
male bettas make these when they are happy and healthy, so that's a good sign.
you can leave it be, and when you're changing the water, he won't mind if you wreck it.
some bettas change color when they are stressed, but since he's making bubbles,
i don't think he's stressed. usually if they are ill or stressed, they lose color and become
pale. his body is getting lighter, but his fins are turning red, so maybe he's just changing
from blue to red. he may be happy, so he's changing, but i'm not entirely sure about this.
i hope this helped, maybe someone else can give you a clearer answer
about the flaring or changing color. c:
