If they are bettas,they will usually hav a labyrinth organ which makes them easier to breath in non-aerated water.So any size tank will be ok i think,i mean they are BETTAS! But i would suggest anything bigger than 10g.Good Luck with those.And tell me a thing.Ehich one is the male and female in ur pics?

Will you be able to see them before you recieve them? Just a thought cause the males would prolly be aggressive whereas the female not. I know how bettas behave, been there done that. Also looking at thier face structure has helped me 100% with short fined bettas. Males usually have a more rugged look to them and a meaner looking eye. Females are less angirier looking. To a certant extent.
