I am not sure what percentage of water I should be changing and if every time I clean the tank do I need to take everything out including the decor and rocks on the bottom and wash them with hot water?? Im just worried doing this will stress him out because its like putting him in a new tank every single time I change the water.
Unless your tank is cycled you have no need for a filter (it will do nothing to help put pick up old food and maybe poop if your fish poops beside it).
I have had a TON of my boys in 2.5 gallon tanks and I always did a water change ever 4-6 days (with Debata he got so stressed if I didn't change it every 4 days that I ended up switching everyone to a every 4 day change).
Bettas build up ammonia fast so you want to make sure you do a lot more than 80%. If you tank is fully cycled that would be the required amount or less depending on what your test say. But since I don't think yours is (takes over a month to get it going) you will need to stick to weekly changes.
Now changing every 4 days may seem like a LOT of water changes but that is what my boy required and so I stuck to his schedule. So with your boy (or girl) you will want to start with a once a week water change. If their fins start clamping up or looks stuff than that means that there is too much ammonia building up in between each change. You really have to work with your fishes schedule and make sure to stick to it.
