Looking after your beta fish in a bowl can oftentimes be a real challenge.
This applies to both yourself and your betta fish. In most cases the smaller the fish bowl the bigger your challenge will be.
So, when you really look at it this way looking after your beta fish in bowl is not really the best way to go.
Bettas Natural Habitat
Although bettas are somewhat accustomed to small spaces they came from little more than shallow creeks and marshes and were even found living happierly in rice paddies in Southeast Asia.
They can breath air from directly from the surface due to there special adaptation.
However, if you still decide to look after your pet betta in a fish bowl it is possible if you... follow these guidelines listed below.
You should change the water in your beta fish bowl frequently since the quality of the betta water is an essential key to a healthy and happy betta.
You should decide to do this often because betta waste and elimination along with uneaten food can foul and pollute the water very quickly.
If you don't remove and replace the water on a regular basis you will reduce the lifespan of your betta somewhat drastically.
Even doing it daily isn't really too often at all.
Another major point for you to remember is: use aged tap water which you allowed to sit in a separate container for a minimum of 24-hours so that it rids itself of any excess flouride and chlorine.
Always make sure that the betta fish water in the bowl or tank is at air room temperature or even a bit lukewarm.
Really, you should try and stabalize it in the high 70s F to the low 80s.
Why Room Temperature?
While we are still on the subject of temperature, you should always put your aquarium tank or betta fish bowl in an area of the room where the temperature is more stable.
Up and down temperature can really have an adverse effect on your betta.
So too is temperature that's too cool. Please remember bettas are tropical fish and do not adapt well to cooler water temperature.
Avoid Direct Sunlight
So again you should **NEVER** place your betta tank or bowl in direct sunlight or in a breeze or cold draft.
Another good thing to remember is: small sized fish bowls although they're cheap and pretty (and, come a variety of colors) you truly are better off with a minimum size which holds at least... five gallons of water.
Ten gallons would even be better still, along with a heater and a safety lid in case you've got a betta that likes to jump a lot.
