They can, but it is not fair to keep them in one. Bettas, like most other fish, like to swim around. A single betta needs a 6-10 gallon tank with a heater and filter for optimum health. Plants and caves make it more interesting for him. A container without a filter and heataer requires constant water changes and has fluctuating temperatures, both of which are very stressful for the betta and thus shorten his life. Just as a person could be kept alive in a large closet, a betta can "live" in a small container, but it isn't fair to judge the space requirements by whether or not they can survive. They actually will live longer, more content lives with more room.
