Yes. 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.
For the best health and lifespan of a betta, you should consider something that is at least 2.5 to 5 gallons and can have a small heater (bettas need a water temp of 78F to 80F), and a low flowing filter on it whether that be a small internal filter, or a small HOB (Hang On Back).
Fishbowl of Love - 2011 The Best Date Ever 1-5 was released on: USA: 11 March 2011
Fish should not live in bowls with the exception of a betta fish that can live in a 2.5 gallon to 5 gallon tank size. Bowls are just too small and are best used to just grow a few small plants inside.
If you betta is in a small tank, placing it in a location that has a warm ambient room temperature should be enough to keep it to betta preferred warmth. If you do not, then you should look at getting a small heater for your tank, but you may need to get a larger tank to allow for the use of a heater as there are no heater models made for anything smaller than a 2.5 to 5 gallon tank.
you can put a betta in a 54 gallon tank
Yes far too small, you should get rid of him.
The only fish you can keep in a 5 gallon tank is one betta (Siamese fighting fish) on it's own as that is a very small tank.
No, it is not.
A betta fish can last 2 - 5 years if kept in a tank with proper conditions.
Yes it should be OK. I would advocate that you use a filter too and do at least a 50% water change weekly.
