How do you clean a fish bowl ( female betta) …?


I do 25-30% water change to both of my 10 gallon chang every week. This is my 1st time owning a betta bowl. So how do i clean the 1 gallon bowl my female is 1inch so she is really small vs the bowl. She loves it so far :). Anyways what % of water change should i do per week or full water. Yea bowls are death taps if your fish is big, but my female is still small guessing a teenage or baby lol so plz answer the question or just don’t. Thanks again =)
You really don’t need a 5 gallon tank i agree it’s better. I’m getting a heater & filter on monday they’ll arrive, but bettas can survive in bowls or small tanks 2.5 if well care.

Thanks again guys for your answers
I don’t need a big tank my female is different she just swims around slow since she has problems swimming the other female swim fast eat swim a lot. If you saw her you will get what im saying i still love her more out of all the females. We are bff.
