when did you add the betta to the tank?
also: fin rot will not go away by itself, i'd add aquarium salt if i were you, do NOT treat with pima/melafix because it can damage your betta's labyrinth organ and ultimately kill it
i'd be wary of adding any tankmates to a betta's tank at all because there's no way you'll know if it's aggressive or not until you do, and you might end up with a tank of dead fish or having to get a new tank for the former tankmates.
tetras do really poorly in groups of less than six-eight IMHO/others' experiences, they're schooling fish and you cannot fit that many in an edge with a betta.
you might want to get fish because they look cool, but you have to remember that they're animals and not house decorations. mistreating them is just as bad as mistreating any other pet, they might not be smart but they can definitely feel.
