I can't get a larger tank sadly. I have little room in my "Fish Room/Bedroom"/ I know they are supposed to have more room but I have seen bettas in tiny bowls live for 3 years and some of ours have lived in 1 gals when they get sick because we didn't take good care sadly. I am certain that our current one will be fine. I tried giving him hidey spots and a hammock and he panicked. He got really stressed and kept going around in circles, er triangles, around the tank until I took them out. I think after he calms down overall, we can add some.
