Water changes for a 5 gallon :)

Hello! I have a 5 gallon betta tank that is heated and filtered. It contains 1 male betta and 10 small Ghost Shrimp. How often should I change the water/how much of it should I change? thank you!!

In a 5gal filtered without live plants with that stocking-nitrogen cycle established.....50% weekly with vacuum should maintain water quality....

Filter media need a rinse/swish in the bucket of old tank water a couple of times a month....
