Siamese Fighting Fish......The clue is in the name
We recommend an absolute minimum of 3gals on our website, so that tank would be fine. We have a couple of similar tanks divided where there is more height and the Bettas use all the space they have whether it be taller or wider. Some people are adamant that 5gals should be a minimum but we've had a couple of boys who were miserable in larger tanks and after a few moves they perked up no end in a smaller tank.
but i guess ill shut up now
