Bettas can live in a 1 gallon bowl with no filter, bubbler, etc. But it is recommended they live in 2.5 gallon bowls or tanks instead. Betta vases are just horrible IMHO (the flower in vase kind - I am okay with just a vase). You can get bettas at your lps or lfs. I know there is Petsmart, Petco, Walmart, and other fish stores out there. But when you buy one - check over that they don't look like they have messed up fins or scales. Also, when you touch the cup they should b startled and looking around at what caused the disturbance. Bubblenests or flaring in their cup is also a good sign when buying bettas. You should feed your betta 2-3 pellets twice a day (I do about 12 hours in between... 10 am and 10 pm) and fasted (not feeding) once a week to aid in digestion. Also,freezedried bloodworms or freezedried brineshrimp are good treats for them once a week or so.
