The red marks on his fins are due to his coloring... he's going to change on you!
He doesn't seems to have fin rot, watch for black edges on his fins... that would be fin rot.
IDK what to tell you about his eating, my fish never turn up their noses on food.
Stop the meds, give him some clean water and keep him warm. Offer him just the pellets, if you're feeding freeze dried bloodworms don't use them again until he's eating regularly and only as a treat. They are not good for bettas.
Great username, btw.
